If there is a group signal that can provide a "perfect" and "accurate" result, damn they might have an effective crystal ball that is able to know what will happen in the future and they can withstand the heavy volatility on the crypto market lol.

Disregarding OP's intention and advertising the posted shared link, newbies should realize that almost (close to zero) trading group signals offering free signals should not be entertained as aside from it doesn't really can predict what will be the flow of the market (as that was tough to do even for professionals) later on, these groups will offer a paid subscription which doesn't make sense to be purchased at.

Remember that real professional traders are too busy with their respective trading works and don't have time to offer such a signal providers.
