No matter how promising a project might look, especially if they are new projects just look them as if they have nothing to offer and invest only what you can afford to lose. Do not keep your eggs in one basket, do not fall in love with a single coin, no matter how good they are always keep digging, many more good gems won't hurt than relying on a single gem 💍. Be smart

There are too many scam coins in crypto projects, trusting only a single coin having higher chance to getting scammed.
