Good morning
Reading about bitcoin, I've found that there is a maximum of BTC that can be mined: 21 milions
It is said that this limit is due to the source code.
As probably you know more than I do about BTC:
- is it a real limit
- is it a good thing? I think it is but it looks like BTC will become more a commodity and not just a payment system
What do you think?
The max supply of 21 million coins is true. It's a real limit, based on the fact that the reward which brings more units in circulation halves every 200.000 blocks. Starting with a block reward of 50 BTC, that means that the current block reward is 12,5 BTC which is true. Bitcoin halved two times, on 200.000 and 400.000 and is currently on 476.502. It's possible to calculate the limit using 50*0,5^n*200.000+x=x, increment n by one and doing the formula over and over till how precise you want the result to be, but in all cases it will come near 21 million.
