To me, the idea of following signals on crypto currency trading is not really a good idea, if one can be steady with the market. Trading on crypto exchanges, sticking to the movements in price of coins, and following the chart of the market will show what can happen next, as it is clear on how these moves act at the particular coin that cut your actions. That is why it is okay to follow up news of coins, than signals, not to say paid signals in crypto. This is my own view, that in forex trading, signals can be followed as it works there, but in crypto currency, you trade what is visible and you have been following it up.
