before investing of course we must choose a project that is really real and can last a long time. such as BTC, ETH, BNB, SOLANA, FTM. this is my choice. besides that you also have to research in more detail whether it's developers, partners, investors, what products are offered and of course don't invest all your money in just one basket and do it with some other coins too.
Looking at their partners, you also have to verify it to their partners by just doing a little research and search if what the project is telling is a fact or just a bluff.
There are projects in the past that are just posting images of their partners and developers but all of them were fake and just for the sake of intention to attract investors.
Because it's making them look like a legitimate project that has the potential.
