It would be interesting to read the thoughts of different experienced people, and their advice or interesting instructions about mining. Let's make this post really useful for others.
I think that this question is repeated over several times but I will say that You shouldn't buy Any kind of crypto mining equipment cause it's no use to mine Bitcoin at a small scale cause Their is so much difficulty that you will end up loosing your crypto and eventually all your hard work will be in vain...
So I will suggest you to go for Masternodes cause these are the bets source to earn money because they are a rich source of money without any kind work.
