I've been wondering for the last days, if mining is profitable? why would anyone want to sell a miner?
If you have the machine to make money, why would you like to sell it? My only answer is that those guys sell the miners when they are not anymore profitable.
What do you think?
- some miners wise up to see buying coins is more profitable than mining in normal conditions. eg. slope of price increase of bitcoin vs hashrate per dollar
-also the factor that preordering for a machine with full capital upfront could be risky, if the rig gets delivered late you loose the edge
- some people selling rigs migh be new to the game with not much capital left after a purchase. New versions of chips serve better value of hashrate per dollar, thus they need capital to invest to stay ahead or else get left behind.
