Hello, everyone!
I discovered cryptocurrencies for myself just recently, so I'm a little late for the party

Anyways, I am interested in mining cryptocurrency, but I am not sure which cryptocurrency has the highest return in usd.
Also, which hardware would provide the highest return on investment?
I have read a few threads over here, but I couldn't find all the answers to my questions.
I realize that cryptocurrencies are very volatile, which means that my return on investment will change as the time goes on.
Mining bitcoin does not seem the best option to me, but I may be wrong. I would like to hear your opinion on which cryptos are best to mine now, and which of them are expected to rise.
Any tips for a newbie miner are apprecited!
P.S. My electricity rate is about $0.018. I think it's a pretty good rate to mine cryptocurrency

Every altcoin will be profitable for you with that electricity rate. Even bitcoin is really profitable for you with that electricity rate. I think you should buy an antminer S9 and start mining bitcoin, that electricity rate is like free compared to what I pay here 0.18$ , you have ten times lower energy cost than me , meaning 10 times better return rate from anything you are mining.
