Hello,
Please help how to avoid some scam bitcoin investment?
I was already scammed 2 times
You should know your wanted project first. Nobody can help you, because money is yours, so you must keep it first, then take responsibility with it.
But ofcourse, in the cryptocurrency world, nothing can be secure. So again, you should spend your time to research what you want to give money for.
Where did you be scammed? I think it could be some kind of HYIP monitors with high interest. And if so, you should stop doing that.
