Look man, it really isn't that complicated if you think about it. Deciding on which is a better choice is so damn easy. All you have to do is to look at your current stage honestly; you can start by asking a question on how knowledgeable are you as of now in terms of knowing things about cryptos? About how they move etc., you can also consider how much spare money you have that you are comfortable on investing? These questions are the things that I think can really help you in answering that question that you have just posted. I hope you got my point. But just in case you didn't, my point is to invest on coins that are low on market cap if you know what to look for to know whether that coin is worth the risks. Or just invest into more sure and reputable coins to keep your funds a bit safer than the other choice. Hope this helps, good luck.
