My question is how long will Bitcoin mining be around for? How long hypothetically until all the Bitcoins are found? Is there a way to know or check how many have been found already and how many are left? And is it true that once they're all found its not possible to make more? Just some newb questions. I appreciate the help.
AFAIK mining is vital for the whole system, so it should go on pretty much as long as Bitcoin exists. Transactions are confirmed by mining and finding block.
When 21 millions Bitcoins are created, block won't give subsidies anymore, but will still be created.
Miners should support themselves out of fees by then. But who can tell what will happen so many decades ahead?
