miner get reward with each block they mined and confirm the transactions
now the circualtion supply is more then 100 milllion for now and its total supply is unlimited but only miners can get few in a year
Interestingly though Vitalik brought up the discussion about implementing a cap to the total supply of ETH.
If I remember correctly it was on april 1st? By the way, if he want to implement a cap (but this question is for all PoS coins) how it will work with PoS ? It's the same thing as PoW where miners get only transaction fees after all coins are mined?
Yes, exactly.
Whereas it totally remains to be seen how something like that would actually play out. Everyone has an opinion on how it will work within Bitcoin, but I think skeptics also have a valid point that once there are only transaction fees the incentive might be too low for a lot of miners to secure the network.
