thanks for your replies, this really opens up different perspectives.

I was actually planning to setup a remote mining rig overseas as where I live electricity cost is almost 0.22/kw.

But it seems it would save me tons of headache by just investing in ETH instead of mining(atleast to start with).

Are BTC and ETH are my safest bet for HODLing for profit? I was also looking at Zcoin(XZC) which rovides masternode(passive income? of $60 a month)

I know its a stupid question to ask what is really safe in crypto, but I would really apreciate if you could share your views. I will take them as 'lessons learnt' by experienced investors and try to atleast eliminate those mistakes.
