newbie often run into losses when investing in new projects. ,i once bought new coins but i can't resell them. i think i have been cheated

what can you suggest to us and how to find out if the project is a scam? Is it true that new Coins can give big profits as people say on youtube channel?
It takes time to do your own research and never fomo buy any coin even the price is moving. Remember that there's a lot of opportunity out there to have profit so take your time to do reasearch and learn how to identify legit project or not.
You can start by doing a background check on the team members then go to the screening of the VC and private investors behind it because big investors never invest on bullcrap project so it will save you time to review the whitepaper word by word to spot shady content there.
