Do You Use Crypto Signals?

There are a lot of Crypto Signal Providers – about 5 of them are at the top of the list.
They claim 80% accuracy.
I googled reviews and I read nothing but good things about them.
If they were bad signals people would give bad reviews.

If they do have 80% accuracy, then anyone who uses them would become wealthy in a short time.
Do you use any crypto signals?
