Often people do not understand the most important thing.
Then what is it? OPs suggestion is the reality. Most projects are just created to mix with the legit ones. Trusted projects can never be really be a trusted one if you dig into it. Btc can be an example. This project seems to be a shit one before but recent adoption proves their mistakr and see where it is now?
Well, the most advanced and fully working product I am aware of is definitely GetHashWallet.
And another example is like this one. How do you even know if this is legit? I think I heard of it somewhere but the point is. You are not sure enough for a certain project and yet you already gain their trust. Always dig deeper to find out all about it. Then speak.
That is more thing to put in mind. Always make sure the credibility of the Team Members of the project. Even if the project has good and enticing proposal but does not have a credibiltiy and trustworthy team running behind it project won't last long and may eventually end up exiting with all the assets in their hands.
