Dear Community,

i found a channel/group where they pump and dump altcoins (https://t.me/AltcoinPumping)
I joined it, but I saw, there are over 16.000 members investing in a mentioned coin (sometimes more than 800 Bitcoins) and I have a little bit fear now, because it´s so big, that I think, it is not allowed.

Is here a expert or something who can tell us, if "Altcoin pump and dump" is illegal?
And how is the tax handeled with pumping profits?

I hope, you can help me, I searched in other boards and in different topics, but no one had a "save" answer.

Greetings, Nacho
