Since all this while that mining altcoins have not been profitable like before i don't bother to keep mining coins so i just lock my mining rig in a room and now that bitcoin halving is knocking on the door i think its a good time to start mining even if its not profitable? i believe if bitcoin surge over 30k altcoins will take the ride we've been waiting for, anyways, what do you guys think? good idea or bad ?
If you are going to mine Bitcoin, then for sure it will be unprofitable. Most likely, you do not have the latest equipment available, and it is not able to give an acceptable hashrate. Only in vain will you spend electricity.
If you want to mine any altcoin, then you will not guess which one to choose.
