I participated in many aridrop projects. It's usually scam and does not pay me. Now should I continue to join the new aridrop project? Please give me your advice.
You already answered your own question, you have been scammed at least once and the language that you use implies that this happened several times already so it is time to stop participating in those kind of scams, at this point even icos that receive funding are looking more and more like scams so a project just giving coins for free is an even bigger scam in my eyes.
