I guess that paid telegram crypto trading groups are just the new HYIP/ponzi scheme.
I wish that Telegram support will find and ban such groups.They really need to clean their platform out of such scams.There are no secret groups of master traders that have 99,99% successful trades and that are willing to share their signals/trades for a fee.This is a myth for the naive noobs.
Telegram group Hype usually for them are fake pump up a group. If you are in their trap you may be left behind on their signal and probably they have big benefits on it. Just, for example, they broadcast to pump xx token will be pump up next 3 days, the day before they announced they already bought on it. IF they saw the exit point profit income they sell for it without further notice to their member.
