have you severed all ties with the DCG family
I don't have and haven't ever had any. Nor have I had any relationship with Blockstream either since I stopped working there in 2017, I think I've told you that before too.
if your not part of the corporate agenda of the barry silbert roadmap of bitcoin of the last 7 years.
I think you let yourself get mislead by people driven by Craig's misinformation man, I don't know else you could have missed DCG aggressively attacking Bitcoin developers with "segwit 2x" crap. Best as I can tell, DCG are shitcoiners that wrap themselves in a Bitcoin blanket when they think it'll make them money (unfortunately like a simple majority of the industry).
and wondering if there is any contagion risk to yourself which you worry about in regards to the effects of FTX on DCG
I feel sad for the retail fools who got suckered into FTX due to all the hype in the media, but FTX's implosion is shaking out a bunch of anti-bitcoin bad actors and I only wish it had happened sooner, I certainly don't have any exposure to DCG.
I do have a nominal amount of my own funds deposited in the LedgerX derivatives exchange, mostly collateral for bitcoin puts I sold there in the last couple months. When FTX.US acquired LedgerX I removed all the Bitcoins I had there and only left a nominal amount of dollars, since I thought SBF was pretty obviously a scammer. ... fortunately appears though that they're completely isolated from the FTX implosion as they weren't integrated and their controls appear have been sufficient to keep SBF from raiding it too. They're operating as normal and I expect they'll get spun off/sold.
with the FTX vs Binance competition.
Like FTX, Binance is another shitcoin casino. Only clueless people do business with shitcoin casinos. All Bitcoiners should avoid doing business with places that primarily generate revenue from selling shitcoins to idiots, and especially from places that offer margin for shitcoin trading. The only kind of leverage that is potentially safe is physically settled options, anything else can easily leave the exchange insolvent.
