Hi Everybody,

There is a new scam method that is getting too popular and many people got fooled so far.

The general idea is this:

1. The scammer opens a fake profile (on Twitter, Facebook etc') of a known celeb like Elon Musk or Ethereum's founder Vitalik Buterin.
2. Then they post an offer that is too good to be true. Something like: "Send me 0.5 ETH and I will send you 5 ETH in return".
3. Some people get fooled and send their coins while the scammer enjoys the anonymity of the blockchain and the fact that the transactions are irreversible.

See how this works here:

Lets stop this! Share with your friends and spread the word.

These fraudsters are making a bad name for Crypto and if less people will get scammed this will eventually stop.

Also - if you have ideas on how this can be stopped - share them below.

Cheers

The subject of bitcoin fees is an important part of understanding how the blockchain works.
Here is are some relevant articles with deeper looks on the subject of bitcoin fees:

This is a hard question to answer because some ICOs were a super lucrative investments and some was a really shitty investment - This is a fact.

See here are the ICOs with the highest ROIs: https://icowatchlist.com/finished/best-returns

Here are the ones with the most crapy ROIs: https://icowatchlist.com/finished/worst-returns

So basically, you can either lose almost all your money or multiply it x1000.... it's not very symmetrical.

That's why it's best to only invest what you can afford to lose but also be a little adventurous - some people made really nice returns with ICOs.

Good luck!

Hope it helps.

Anyone...?

Hi,

After some digging I still don't understand some major stuff about Ethereum and I hope someone can explain the following:

1. The miners are executing the smart contract code - right?
Does all of the miners in the system execute all the smart contracts code? And if so, how is the system able to scale and keep writing blocks every 15-17 secs when more and more contracts are being created?

2. In bitcoin, the miner that gets to write the next block gets it because they where able to find the solution for the specific hashing problem - how does this work in Ethereum?
I mean, how does the execution of smart contracts code and hashing the blocks works together?

3. A DAPP is basically a collection of smart contracts that work together and sending each other ether to run and do specific tasks - right?
If I got this right, what happens if someone else sends eth to one of the components (smart contract) that shouldn't run separately?

4. If I build a DAPP (let's say a new ERC20 token) - and I have only 1 ETH to use - how this affects my new coin?
    Or in other words, how does the ether currency relates to these erc20 coins? When I buy or sell Golem for example, how is ETH part of that process?

5. Bitcoin has a limited number of coins - how does this works here? When are ethers created and is there a limit? What are the rules?

I really hope someone can help me.

Thanks again

Thanks again Foxpup,

You said about the fee amount:
Isn't this a very similar number of bytes for each transaction? I mean, it's simply adding or removing numbers for public addresses - isn't it?


Another question in that path: Once I send something bitcoins, where does my transaction goes to for all the miners to grab it from?
I understand that all the past data is in the blockchain, but where is the data that is still not in the blockchain?

Thanks again!

Thanks Foxpup, I really appreciate your help!

I have more questions now..

Fees:
1. How are those set and where? Is the fee set on each transaction? Can I choose to pay as much as I want?
2. Is it percentage or fixed?
3. The miner of the latest block gets all the fees for the transaction in that block? Or is it more complicated?

Thanks again

Hi,

I'm into bitcoin and crypto for a few years. And getting more and more into this space.

However, there are things that I still don't understand about bitcoin and blockchain in general and I think others will also appreciate learning about.
I hope someone can help me understand the following:

1. Bitcoin block size is limited to 1 MB - right?
So what will happen if the amount of transactions in last 10 minutes will not be able to fit in the block?
Or for example if someone malicious will run a loop script that opens millions / billions of addresses and send them 0.0000001 BTC to clog the system...?

2. As I understand - The blockchain's ledger doesn't have my wallets total amount - it's only documenting the transactions.
So to know how much BTC my wallet has - We have to calculate everything from the beginning of the blockchain, or at least from the first block of my wallet's address - right?
If this is true, how come it's not super slow once the blockchain in very big?


Thanks!
