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
It is not even wise to follow what you just read, so the best favor you can do for yourself before investing is to DYOR. Most people would advise you to invest in this coin, this coin will be worth investing in long-term, etc. Take note that most people advise to buy a certain altcoin ecause they are holding it, so it is more on shilling not an advice. Just stick to the basic before investing, your time invested in doing your homework before investing will be worth it, than just following other people's advice.
