If you want to invest but do not know what to invest in then it is better to save money and do not spend it on advice from the Internet. Buy some bitcoin and don't buy the rest before figuring out what you want to invest in.
buying bitcoin will be easiest decision while we confuse how to pick altcoin in market, as major coins in crypto currency market this coin have alot potency to growth every year with mass adoption that regularly coming in several countries.
The coin you mentioned are good tho but for me I don’t really believe in those projects, I feel no much hype and utility so far, I did go for projects with more hypes, back ups , use cases and also projects which really solves problem in the crypto space , that’s why am really bullish on coin like $Near, got a readable wallet which would help newbies reduce the complexity of wallet address, and also a scalable and interoperability blockchain which gives a complement to $ETH.
your reason was acceptable for most crypto community. utility and usecase in their ecosystem will be the key how this project will builded and bring solution for any problem in crypto market.
