Do your own research
I dont think its smart to get crypto investment advice from forums most of us here dont know what we are saying and most of the advice you will get are going to be coming from other noobs just like you.
The Best advice i have is do your own research, if you dont understand it, dont invest in it, its better to miss out than to loose your money.
Remember investments are risky, so why trust other people's opinions to making investments that they aren't making with their own money?
Be smart
Don't be greedy
Take profit once in a while, if you see 30% - 50% it's already a good return.
Don't put everything into one investment spreading your money will save you a one-time loss.
Ask questions to those who have a big portfolio, why? they know when and where to invest, this is the thing that others forget, they thought it will degrade your pride by asking to those who have established trader, its okay to accept that you don't know everything that you are just a beginner, and you needed help.
This is what I can add.
