Okay, so I have stuff coming to make my first GPU and CPU mining rig. It's not gonna be anything impressive. So the capability of the rig is not really my top concern. I do intend to mine up to three different coins at the same time for the same duration.

My priority is to diversify, like I have with my other portfolio and has worked well, so I feel to do the some with my crypto holdings.

I'm not trying to chase profits, so the kind of coins I'm after are ICOs/emerging projects. Mine the algorithm(s) for about a month and hold the bags I accumulate long term in hopes one of them will .
I'm to understand about 90% of new coins will become failed/dead projects.

When it comes to the number of coins out there, it's a veritable ocean. I have seen where I can find lists of new coins, like coin market cap, but it would be hard to know which ones to choose.
I'm looking for some advice on how to look for coins to try to mine and tell which ones to avoid.
