Mining Payback Mechanics

[obszoenling]

Hey everyone,

I got two questions regarding the mining of crypto coins. Bitcoin has a max supply of 21,000,000 BTC. When this number is reached, how will it affect the mining? When there are no coins to mine there is no point in mining. No mining = no transactions.

I heard that it gets more difficult to find new coins the more coins are already found. How does this affect the mining in general. Since the mining payback is not linked with the coin price, mining with lose efficiency the harder it gets to find coins.  How is this handled?

miners will *mine for transaction fees whilst keeping the network secure. alot of things can happen between now and then. haha

In the far future all mining will be for transaction fees, as each halvening takes reward down until zero. As difficulty rises as more blocks are found, ASIC producers make their chips faster and more efficient. We are seeing diminishing returns in efficiency as time goes on due to the fact that we have largely caught up to the mainstream semiconductor industry and we now have to actually wait for new processes to come out.
