Unfortunately this is no sign of it being hufflepuff. Huffle got enough BTC to sustain his life I guess and from what we have seen , it seems like just another normal player playing with alot of BTC but with much more safety precautions by betting on the small multiplier

P.S : thoughts this is clear that he is the legendary gambler mech


It is highly unlikely that this is an inside job because if what you meant is that the operator of PRC is playing a hand on this as well , then I doubt it is. Theoretically this is possible however it will be much better for an operator to "leech" the investor funds in a smaller amount to make it looks less suspicious ( this is too suspicious so I doubt its him )

P.S : he would want it to be more suspicious if this is an inside job ( although to be honest , I dont think he did )
