The incentives to mine are: newly created coins and the transaction fees. Even when all coins are mined, the transaction fees still belong to the miner.
mskryxz: the algorithm behind Bitcoin (SHA256) is useless for "genome, dna, ai, weather modeling". ASICs are not reprogrammable, the algorithm in them cannot be changed.
I am asking when all 21 million coins are found though....who's going to mine then?
the people who own those 21 million coins will probably keep some hardware or pay for hardware to run to keep the system alive
