They were all blockchain txs, so there's no chance of fabrication. Imagine, you have received x amount of BTC in an address from betcrypto¹, and later, betcrypto found a link between the withdrawal address and a new user deposit address, there's nothing you would think of I believe. That's what happened. I requested betcrypto to present all the proof here. They told they will share so, allow little time to them so they can post the proof.
