welcome to the community

1) my first bit of advice would be to always do your own research instead of just going off of what people say online
2) best things to research about a project is the whitepaper concept, the team, the roadmap, and how far along they are (I'd rather go for a cryptocurrency with a working product like Ethereum, Plutus, Stellar etc. than the ones who only have a whitepaper as they tend to be more legit)
3) trading is not easy, it takes a lot of time which I don't have (crypto comes 2nd to my actual work). I do however have faith in crypto so I prefer to invest and hold long-term
4) Do keep your coins somewhere safe and secure (best option is a cold wallet), centralized exchanges are not liable for anything that goes wrong
5) Don't chase the cryptocurrencies that have just skyrocketed as tempting as it is
6) risk management is the key
I don't know how much you know already but this is just a few that popped into my head, i'm sure the rest of the community will have some better pointers
