What should I look out for before investing in new crypto tokens?

I like the fact that the crypto market moves in cycles, as that opens the door for new investors to come. I feel what this also does is that it affords new tokens to get launched and they become attractive in just a short while.

So while I hold some Eth, bitcoin and some other major coins, I also pretty much fancy the idea of Investing (not huge amounts though) in some of the newly launched tokens. I see them being able to multiply my investment in a short time if my selection goes right by the way.

So what background checks do I need to conduct on the likes of snipcoin token, TokLok Token, proton token, Metal, Foobar and GMT… before finally picking two or three of the bunch.

And BTW, I'm very much aware that all of them could eventually turn out to be shitcoins… or they could turn out to be gems. Guess it's a 50/50 probability
