So /biz/, why shouldn't I join this pump and dump groups on telegram and then just short whatever they're pumping?
Because you can't call the top.

good point. However, I'm in a group and they 'announced' the coin at 6pm GMT. The coin has already been pumped and then absolutely plummetted
Because they use shitcoins on bittrex or yobit, no margin trading there.

ok then
because there's good chance you'll just end up holding some Indian guys bags after you pay to pump his coin
