Because of that post maybe others will enlightened about earnings in doing a physical bitcoin mining. Today it is really not profitable especially after halving and you will just start from a scratch.
90% of bitcointalk member sure bitcoin price will be up "beofer and after" halving block, and old miner can take profit if the price rising again,
but for me the true problem Is after Bitcoin halving the reward will be down even the bitcoin price up, the reward is very very low and i doubt new miner can reach ROI ..................
