Nice one..
It's pretty easy to use and great one..
A Simple mining calculator it is..
I don't see any major problem that need to be updated..
At lowet level or normal calculations it can be used..
Otherwise for more bitcoinwisdom mining calculator id there

Not so..
This is just a bullshit..
He doesn't believe in bitcoin so he sold it and prices go down..
There is nothing like R.I.P to.bitcoin or.bitcoin is dead..
And it never can be..
Instead it's a good time to buy btc for cold storage or future usings for trading..

They are not hiring..
They are trying to study about crypto..
And they are also trying to take governmental control on this..
But as everyone knows.. not any government can take control over it..

For me.. not so major problems..but sometimes I think about what kind of problems could be occur..
First one is.. time for transaction confirmation sometimes..
And any option to stop transaction if it is not confirmed..
There should ne a option to cancel transaction as soon as before confirmation..

I have 0.2 Bitcoin maximum till now.. and that time i only used for a payment..
When I started earning it.. i know now its value.. and never wasted it anywhere only legit use..

Oww media.. they only want a way to make issue..
And if mike Hearn doesn't believing in bitcoin then no problem ..
The time will tell everyone the future...
It's global revolutionary gold of internet.. not only a people can decide the future of it..
And it's a great time that price has been decreased let's buy bitcoin to store them for a price increase..

It should be right to believe that only limited quantity of btc is there.
And one time miner won't able to mine..
But think bitcoin transaction will,never end.. so being blocks will never end and the transaction fees in blocks can be mined..
It is true that difficulty will increase but I don't think there will be a rigid stop to mining..
Possibly there should be low profitable

Bitcoin is more than real money to me..
It has opened every boundaries to me which fiats can't..
Like instant transaction anywhere in the world..
Unlimited transfer without any government control..
Lower transaction fees as compared to fiat..
Secured too much other than PayPal or WU which can be hacked..
And i can do mining, cloud mining, trading, earning, gambling with btc easily..

And western union can easily be hacked...
If you have seen, i have senn many hackers hacking western union money WU and selling them in change of btc..
Because they can't hack btc or they can't use stolen cards there..
The blockchain is too much secure than other all..
That's why they sell hacked WU transfer in change of btc..
And btc has fast transaction, lowet transaction fees, and open easy use, no government controls..

Yea.. bitcoin transaction is at low fees..
And that market user comparison,
Western Union, Visa and other cards had years of time to grow,
And bitcoin has just started..
Wait some years...
When all people will know about bitcoin and for banks of bitcoin..
I m sure bitcoin will be in top 5 if it happens in 10 years period..

I have bought bitcoins but that time when i only considered bitcoin as a worldwide transaction method..
And i bought btc to pay someone ..
Then when i came to know about trading and mining etc of btc..
I started earning it mainly for a trading capital..

Yup i would also be happy if it becomes worldwide using currency..
And can be used everywhere..
But if it will centralized than what about fiat as said above me..
And if bitcoin remains as it is.. well i have never thought about it that anytime it will be stable..

I also suggest you to delay your deal until transaction gets confirmed..
And wait for few days more..
Sometime it happens when there are too many blocks or depends upon transaction fees..
So wait otherwise it will be double spending for sender...

I'm pretty impressed on this for bitcoin..
It proves that nowadays big transaction are done with bitcoins..
And too much people using bitcoin..
And second thing they chose bitcoin over banks.. as bank limitations and government controls are too much..
They believe and trust in bitcoin..

Great... happy birthday to bitcoin..
I would thanks to satoshi nakamotta for his incredible contribution to bitcoin..
8 Years of bitcoin..And I'm still in the bitcoin since last year..
After this great achievement bitcoin is going to be global currency soon..

For trading i prefer:
Yobit.net
Lolcalbitcoins.com

For mining i prefer:
Eobot.com
Hashnet.com
Cldmine.com

For price check i prefer:
Blockchain.info
Google.com

There are many things about bitcoin..
So start with explaining btc as a online worldwide transaction method to normal people and a source of trading to a marketers or traders..
And then they will personally take interest and they will explore it themselves by own work or slowly teach them about trading , mining, hash , blocks, gambling, etc etc..

It is more than real money to me..
It gave me freedom to pay anywhere in the world
And ways to increase my money like trading, mining, gambling etc which i never thought to do with real money or fiat

I only would like to say bitcoin future is very bright in comparison to other crypto currencies so far,
And wait till people of whole world know about bitcoin..
And bitcoin banks..
Then you will know about bitcoin future

Well history tells us, where we going in future, because history repeats itself.

My prediction - BTC will become the de facto digital currency within 2 years. King of Coins. {Not just on dominance, but retail acceptance, and track record}

But BTC will not stay there for long. Someone will create the perfect coin, for governments to manipulate, and they would find ways to regulate people, to force them to use that.

People have too diverse views on poliitics and other human factors, for them to adopt a single currency world wide.

Until then, we ride the BTC wave, and then climb onto the next wave, whatever that will be. Currency Surfers.
