That's the only way I can think of to avoid crazy counter party risk.
As to it going up today, it's still a 20b company with huge operational costs and no profits operating in funny money world full of scams, regulatory risk and having very little growth potential (after 13 years of crypto there is still no use case other than going around or breaking the law and it already reached its Super Bowl ads state so it's not like any more adoption is likely).
Yes, you already missed the biggest gain as it's already worth about 25% of what naive public paid but there is still one way to go.
What kind of an impact are we expecting on, say, Coinbase?
On top of that, Coinbase needs a stable coin to operate at any non-trivial scale.
I'd say the impact would be severe. That is unless crypto investors just pretend nothing happened, and some other bullshit stable coin immediately takes care of the liquidity issue, which I'd call likely.
