There are some making crypto signal group as a business, also
it is a way of helping traders with no spare time on their hands,
so somehow it is a win win situation.

joining/entering a crypto signal group is costly and risky, why
not learn trading by yourself? you don't have extra time? well
if that is the situation, just a piece of advice, be carefully, have
a proper precaution, don't rely and trust signal group too much.
