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 do you mean? You cannot resell because the value is too low now that you're at a huge loss? Or is it because it was delisted? Quote
what can you suggest to us and how to find out if the project is a scam?
Majority are either scams or just plain useless. Don't buy any of them if you're a newbie. Stick with BTC.Quote
Is it true that new Coins can give big profits as people say on youtube channel?
Ignore youtube channels since most of them are only good on a bullrun. They disappear or go silent on a bear market. You don't need them. Just understand that probably 80 to 90% of tokens pumps on a bull market. On youtube channel we can not say that the people who are you looking at is a legit and trustworthy. Even with thier words, we can not assure that they are legit and the site or the coins they promote are good to invest cause nowadays many sites that offer a good amount of winning but thier are scam sites.

1. First thing is to do your own research and just rely on what you hear. You can do this by visiting the project's website and check there white paper, it explains the project plans compare and verify your findings from other sources
2. Avoid projects that promises huge gains in just a little time frame. Due to cryptocurrency volatility just like the stable coin like Bitcoin it takes gradual time for investment to mature.
3. Another thing to again is to check the project community, the project's management although some project actually use influential people to promote there project. You should be moved by that but calm down and do more findings.
Lastly there are lots of scam project around so as a newbie I would strongly advice you to invest in stable coins like Bitcoin and other stable alt coins like Etherium and BNB. Just stay away from quick rich projects
