80% of all available BTC is now mined. How long will the last 20% take?


#1

until 2140!


#2

The blocks are being solved on an industrial scale now. With all that competition, I just can’t imagine how difficult it will be in a few years to mine this stuff. And with the rewards halving, how is this sustainable?


#3

Miners will drop out and switch to other currencies, that will make the blocks easier to solve, and once again profitable.


#4

Maybe overall, yes, but when the reward halves in less than two years it will be interesting to see how the market absorbs such a big change overnight. Since everyone knows it’s coming, maybe the change will have little effect.


#5

Previous halvings of Bitcoin didn’t rock the boat too much.
