Maybe the title isn't as obvious as i want it to be, i wanted to know from people already investing in cryptocurrencies how to decide/research which coin is worth the money and which is not, what does it take for a coin to look successfull, strong code? Dev support? Most importantly, how to decide where to invest rather than taking advice on what to invest into.
To me where to invest / what to invest into mean pretty much the same thing.
So you asking for advice, because you dont want to take advice, would seem nonsensical, to my mind anyway.
