since they received a lot of altcoins, theres been a lot dumps and cheap alts, which makes me think that they dont lie about how they get their profit
dump the alts that investors deposit causing a shakeout, buy back more of the same alt much cheaper with investors' btc deposits, sell some of that alt at the top if it pumps again. Everybody wins and they keep the change. This business model is much more sustainable in the long run without having to conduct any fraud. It just doesnt make sense for them to go ponzi as its only a short term profit. Why make less when you can make more.
