Had the same experience yd. I clicked instantly (same group) and it was alrdy to late. My theory: He just scams everyone and puts on his sellorders, so all the FOMO users buy his coins for 200-500%. I clicked instantly when it was announced and the coin was alrdy 10x. So this only works if you get the info before. otherwise its way too late
