Understanding the conflict or collusion between FTX and Alameda, the ruins of SBF's collapsed empire, with DCG's Grayscale is complicated.

FTX dumps GBTC

     FTX held 22 million shares in Grayscale Bitcoin Trust (GBTC); those shares, worth approximately $1 billion, have now been sold by FTX. This may be considered part of the liquidation of a bankruptcy. After this dumping, the value of BTC in the crypto market fell to the level of $39k.

Alameda drops lawsuit against Grayscale 

     FTX's sister company, Alameda Research has filed a lawsuit against Grayscale, alleging Grayscale locked its assets worth $9 billion. Now, just hours after FTX sold its stake in GBTC, Alameda dropped that lawsuit. After this, Grayscale announced that Alameda's lawsuit was meritless, which Alameda itself accepted by dropping it.

Agreement Settlement 

    This behaviour of FTX and Alameda Research seems likely to indicate collusion with Barry Silbert of Grayscale. They were ostensibly fighting among themselves in the name of investors' interests, but internally, they compromised among themselves for their own interests. If SBF is going to jail, it doesn't matter to others.
