I have been in many such paid groups, but to be honest almost all of them are crap.
The problem.
but I am looking just for Bitcoin prediction, just to buy/sell without leverage and with clear instructions where should I buy, where should I sell, stop loss and so on, but as I said, I just need basic BTC price predictions.
Maybe someone is a part of such a group and can recommend it?
And you want still inside into the problem.
Just start trade with your own speculation, technical analysis & fundamental analysis. If you don't know the reason why you buying, selling & holding your crypto then you should not really suitable for doing a trade/investment for the coins.
