You either make your own decisions through research and thinking, or don't trade at all. These "bitcoin signal" services are 99.9% pure bullcrap anyway. If I could predict bitcoin prices accurately, do you think it would make sense for me to announce my "predictions" in a group? Of course not. I'd take advantage of it for my own.
Yup. 99.9 is probably optimistic. I've actually paid (yes, I was foolish too) for a really exclusive and expensive group calling themselves whales and in business for years, out of curiosity. Just kind of glad I paid when BTC was rather high (but still wasted a lot of money!). I actually got told blatantly I chose the only 3 months they have ever been in losses, didn't refund nothing just gave me a lot of very nice words and apologies. They promise all kinds of things, all kinds of transparency but apart from typically flavoured good English and professionally written copy, they really are no better than the free TA and signals you can find right here on this forum from serious enthusiasts.
You're better off just using the predictions in micgoosen's Qx games running on Speculation. Seriously.
They're just legal scams, seriously.
