Nope. Not even a single penny. I did my research. They looked very dodgy - so I never went for anything they were advertising - and I have encouraged others to avoid them. I do love the blackchain technology, though - so it really pisses me off when I see people who are using a good thing for bad purposes. Cryptos don't need a "black eye."
I did get taken for a ride... 25 years ago, by somebody else. Learned my lesson then. Hopefully, I'm trying to educate people so they don''t have to deal with a similar experience. And, these guys fit the profile of scammers - in my experience.
