Do you know any sites with Bitcoin / altcoin signals?
There are a lot of signals in telegram, free signal, and paid signal, I follow free signal because for the paid signal is nonsense, the cost is too high, but not 100% free signal that I follow will give profits, sometimes also end with the loss. I'm sure paid signal also no guarantee for 100% profits
You don't need a trading signal in cryptocurrency, you just need to buy and hold
