Re: Question about hacking and private keys - Coinbase as example

Coinbase has several wallets and private keys. The private keys are required to send the coins between their wallets and to wallets they don't control.

When you buy bitcoins, Coinbase credits your account when the money is received from your bank. No bitcoins are moved.

When you deposit bitcoins in your Coinbase account, you are sending to a deposit address in Coinbase's wallet. When Coinbase receives the bitcoins, they credit your account. They know which account to credit because only your account uses that deposit address.

When you send bitcoins from your Coinbase account to a friend that has their own wallet, Coinbase debits your account and then uses their private keys to send the bitcoins from their wallet to your friend's wallet.

When you send bitcoins from your Coinbase account to your friend's Coinbase account, Coinbase simply debits your account and credits your friends account. No bitcoins are moved.

When you sell bitcoins in your Coinbase account, Coinbase simply debits your account and transfers the money to your bank account. No bitcoins are moved.

I hope that makes everything clear.

You have just explained how the process works which is not only peculiar to coinbase but all of the exchange site operating in the market. What Op is asking is that what is the usefulness of the private key if its possible for someone to convert bitcoin to cash without the need to submit it somewhere or verify it.

The simple and straightforward truth is that private keys are to establish ownership. When one wants to bid for a project and you are required to have certain amount of money in your account, there only way to verify that is to show a verifiable bank statements not your flashy cars, wristwatches, clothes or chains. The same thing here in the case of bitcoin while bank statements can be forged, bitcoin messages cannot ( to a large extent) and keeping funds on exchange sites does not give room for that.

 So yes you did understand perfectly what I was asking Smiley  but the last sentence kind of confused me. So are you saying keeping it on an exchange is a good thing or a bad thing?

“Perhaps you believe that each bitcoin has a private key. That is not how it works. In simplest terms, an address holds bitcoins and an address has a private key.”

 Absolutely I thought that each BTC, LTC, ETH, etc,et, had a key???  That’s just kind of blew me away!!!

When you have bitcoins on a Coinbase or similar account, you don’t actually hold bitcoins in a technical sense. It’s like having a tech-savvy friend hold your bitcoins. Coinbase, or your friend, has the private keys to the bitcoins (actually to the UTXOs) you have deposited, and you trust them to eventually give you back your bitcoins by sending an equal amount of bitcoins (but probably not the same original UTXOs) to whichever address you specify.

Keeping your UTXOs in a wallet of your own is another thing entirely. You hold your own private keys and are responsible for keeping them secure.

Kind of...  but I understood your explanation the best Smiley  I guess maybe since I don’t actually use them for anything other than investing then none of this really applies to me is what you’re saying? But if I buy things or do other things with them, then the keys are essential??

I mean I’m sitting here thinking, reading all of this research about how coinbase is almost virtually unhackable, because they store the keys in an underground vault that’s inaccessible and has never touched or will touch the internet.  But if what they are storing is not needed to cash...

OK so after reading everyone’s replies this is what I get out. At the point where I buy and keep them at Coinbase  or send them to another Coinbase account the keys are never involved. But if I decide to send the coins to another exchange, then the actual keys are in fact sent at that point? So that means if somebody were to hack into my account and transfer the coins to their account, then at that point the keys ARE sent along with it?

So my understanding is not correct and my “keyless” concept ONLY applies to me keeping it all local on the Coinbase exchange, correct?

Then if that is all correct, the only question is why does Coinbase tell me I cannot get my keys?  That can’t be true then and that’s what made me think the coin‘s were not sent with the keys because they say they’re not available to me?  But they are available to absolutely anyone else when they are sent?

Question about hacking and private keys - Coinbase as example
by

on 16/02/2018, 06:57:18 UTC
Don’t really have a good understanding on all this stuff as far as the actual mechanics behind it. But something just really doesn’t make sense to me and it seems very amiss.

Let’s take Coinbase as an example. If coinbase is only a hosted exchange and doesn’t actually have the keys available, as they are held in cold storage, then what good are those keys to begin with if they are not required to convert to cash?

If someone was to hack into my computer and take control of my account and transfer my coins out, they don’t have the actual keys, they just have the coins that are keyless, yet they can trade those coins without the keys and cash them in.

So what the heck good are keys if I don’t need them to convert to cash? They seem to be totally useless if somebody can just steal your keyless coins, put them in another account and then convert them to cash without even NEEDING the keys. That seems like a major flaw to me??

For strong willed traders, now would be a great time to get in to bitcoin as there are large fluctuations, so winning big is a possibility. Sadly, they turned the market into a playground and investment is out the window. Hopefully this normalizes a bit soon.

I'm with you my friend and I started buying when it hit $7800.  The good thing is, as it drops another $1400 like it just did, as long as you go ahead and buy MORE, you can cut your losses dramatically. Of course we don't want to follow that zero..

2/3 of the problem is the freaking media and idiots like above with the warnings about cyrpto Armageddon which scares and stops more people than it should in their tracks! Me?  I'm not going to miss another chance of getting rich even at the sake of losing it.

The pain of losing my ivestment will be MUCH less than the pain of not investing and knowing  for the rest of my life I had another chance but didn't want to risk it..

I've been reading these warnings not to buy so long I just ignore them. Almost as much as I ignore what ripples going to do Smiley

But this particular guy?? He really takes the cake with this absurd and ridiculous warning because its based upon absolutely NOTHING, other then a thought process that you should wait until you buy it AFTER it becomes well-established.

WARNING!!!! DONT BUY MICROSOFT FOR $1 A SHARE UNTIL IT BECOMES POPULAR AND WELL ACCEPTED BY EVERYONE!!!

Yeah right, great advice, don't touch it until it goes back UP in price and stabilizes. Don't buy it while it is low!!!! What a ridiculous strategy. Once anything stabilizes we know that it safe(R) to buy. But once it stabilizes it's has also reached its value and no longer becomes a great investment, just a mediocre one that pays very profit yes, but very little.

Just another dumb crap trying to act like an asspert.

Re: New to crypto. Should I buy Tron TRX?
by
Plumberman
on 30/01/2018, 11:21:37 UTC
Absolutely disagree. Most of the posts here seem to be people that are buying into the rumors but have no actual first hand knowledge of what they are saying is accurate. TRX is not a good buy. It's a GREAT BUY. Just don't go full retard and be willing to wait few months. Personally I think at the current price, it's a no brainer to get some. Time will tell. Other websites if you posted that question, the replies would all be YES. This seems to be a particularly anti-Tron crowd here Smiley

Advice here to buy XRP??? That tells me too much buying based on hype and rumors.  XRP has been hyped over and over and over and yet?? I say let it speak for itself. XRP isnt speaking... TRX HAS spoke more!

No one puts together the team that Justin has if the coin is a fluke.  And the talent that he has hired would not be joining his team if the coin was a fluke.

That's the number one sign this coin is getting ready to do things. The list of people that has joined Justin are in the TOP of their field. He has had some of the most well known and respectable talent in the field join the Tron team. And not just one or two. DOZENS.

This coin is being hyped as a loser so the price will go down and others can buy low. Do your research and you will see what I'm saying is true. Don't take my word on it or anyone else's.

IMO, there aren't too many  better deals in the market right now than TRX at it's current price. This is a "get rich" coin.  The coin is currently ranked number 14.

Justin has a constant presence on Twitter.  Has been in Forbes. Really going to say TRX is a joke with this talent??  This is one of the most undervalued coins available!

My overall advice to you would be to not come on to a website and ask "others" their opinions about a coin. All you are going to get is a minuscule sampling of a few peoples opinions that don't represent even the smallest  recognizable fraction of the people out there buying a certain coin.  And then you will allow yourself to be influenced by a couple of post giving YOU advice about YOUR money.

These people telling you what to buy or what not to buy, how successful are they? Did they just retire because of what they made off the market? You don't know anything about these people. Formall you know they live in a one bedroom efficiency and barely making ends meet and throwing out advice to YOU about what's good and what's not!

That's real nice I like!!!! So they have their own presence here to answer questions directly? Coinbase do that also?  This is a pretty cool site I'm glad I found it!!!!
No. This user has nothing to do with Binance. Pay attention to his links and you will see that he just created the thread to grab some referrals and earn the 50% comission Binance offers.

And I am returning 40% back to the user. Read the thread.
Never said you weren't. Just said that you don't work for Binance and want referrals (which is true). Read the post.

Sorry I didn't get a notification that somebody posted. Thank you for bringing that to my attention and yes, I do find that somewhat deceiving.  Best to just say you can ask your questions here and it's also a thread I created for  referrals if you're interested.

Re: 10% Deposit Fee Coinbase?

 I made that mistake once before and it will always upset me.  Very first purchase I ever made was a month ago or so and bought 15 LTC at $176. Week later it got close to $400!!!  Being new and not knowing any better I didn't do anything just figured that's the coin world.  Had I actually studied the coin that I just bought instead of only buying it because it was the cheapest going on Coinbase I would've realized that was an all-time high and sold it for a nice tidy $2,000 profit.

 It's amazing how much I have learned in the last 30 days and still have so much more to learn Smiley

I tried to post a screenshot but I guess that option isnt open.
Says sold: 6.58 /$1801.81
Price $277.97
Payment method: My bank
Fee: $27.25


 I was even more shocked they only took 24 hours

That's the 1.49% Buy/Sell fee.

In that particular trade it was a bit less, it was 1.39%.

That's far from 10%, you need to practice more your math skills. Smiley

https://support.coinbase.com/customer/portal/articles/2109597-buy-sell-bank-transfer-fees

 You need to practice your reading skills, I already addressed that 1.5 % in my first post... and that's NOT a buy sell price because it was already purchased and sitting in my wallet!

Yap, I got the percentage wrong, it's 1.49%.

If you sold 6.58 LTC at $277.97 each litecoin, that's $1829.04 and when you deduct 1.49% fee, 1829.04*0.9851, you got $1801.74, and the fee is 1829×0.0149 which is $27.25.

If bank transfer is free, you get $1801.74 in your bank account.

 I guess what's throwing me is what I had understood ( which is wrong of course Smiley that they consider depositing the money back into my checking account "selling". So I had the coins in Binance and I paid a "fee" I guess to exchange it to Coinbase. So now my coins are sitting there and I say "hey, let's deposit it back into my Acct"

Don't ask me why, it's stupidity on my part, but for some reason I never thought that was actually selling!  Came from the notion that I was doing a lot of buying and selling but never cashing it out. I would sell, but the money would go into the account and then I would buy something else with it.  At that point all the fees are paid unless I want to buy something else.

So Lesson is learned.  Cashing out to put it into your checking account or buying something else is the exact same thing and for some reason I just did not think of it like that.  For some reason because it was already in my Coinbase account all I was doing was " depositing my LTC into my checking account with all fees previously paid"

In retrospect it was a pretty dumb way to look at it because obviously I need to sell the coins in order to convert it into cash...

CRAP!  Now that means I need to Learn to read.. LOL

10% is too much and incorrect.
I am pretty sure you used the coin base USA for this exchange.


I'm not sure what you mean. It was pretty simple. I hit sell LTC from my Coinbase account, chose deposit money into my checking account..  all over.
Of course  I did it in USA.

 I wonder how many people know about this? If most people are like me the money stays somewhere other and not many people are depositing the money back into their checking accounts so it may not be more widely known.  That sounds like a terrorist kind of charge. Like they're holding your money hostage. Well if you want your money back you HAVE to pay us a "release hostage" fee

I keep my spending btc in gdax till needed and I moved some btc to play with the Shift debit card.
Just a quote for selling 0.00164800 btc on coinbase.

0.00164800 BTC $24.31
Coinbase Fee $1.49
Total Payout $22.8

I see what your talking about, coinbase calls it a "Conversion Fees"
https://support.coinbase.com/customer/portal/articles/2109597

From what I can tell, its a "Conversion Service."  It looks like an add on fee for making it easy to trade.
Perhaps use gdax limit sell and ACH withdraw to avoid that fee.

Thanks for sending that link because I was unaware of it myself. I have made 100 different buy/sell back-and-forth from Binance to Coinbase and the fees are not even worth mentioning they were so cheap.  It's why I had a heart attack when they charged it.
 
I find that to be totally unacceptable!  Just ridiculously high!

It's the first time I have sold! So do they really, seriously charge TEN freaking percent to sell?  Oh my god that's a lot of money!!!!  So if I happen to hit it big and I want to sell $20,000 worth, CB is going to take $2,000?  That sounds like highway robbery to me.

I've sold and withdrew from Coinbase a few times, fees are negligible, don't know what you're talking about.

Are you from USA?

Maybe it's you're bank taking the money.

I'm not sure what you're saying? Other than maybe you consider 10% negligible?  I do not I think that's extremely high to sell.

10% Deposit Fee Coinbase?

on 08/01/2018, 11:22:36 UTC
I sold 6 LTC and deposited it back into my checking account. Was $277 LTC and deposit was $1800. Fee was $27.25??? WTF??? Website says ACH deposits are free? Are they charging to convert the money or something because I already paid the fees when I put it in there to begin with.

It's either 1.5 percent checking account fee or a whopping 10 percent LTC fee. Since it was $277 and $27 assuming it's a 10% which is outrageous!
