Of course, not all new projects are bad, but new projects are very prone to scams because during the pre-sale of tokens they could run away after collecting funds from investors. Therefore, it is very necessary to conduct in-depth research before investing in a new project and of course, you must be prepared for the risks that will be faced.
perhaps, it was a very usual issue that we experience in investing in new projects which is very alarming or discouraging people to invest in them.
If I invest in crypto, I'd never spend a lot of time digging and searching for legit new projects but directly go for known and potential coins already like BTC and ETH. Because it found out that even if we do research this won't guarantee safety, many projects have a good start but in the later part, they turn into scams.
