I'm guessing Joltz is the closest? Weeks away? Or already in the testflight?

His thesis is that USDT payment volumes waiting in the wings for the Lightning Network (due to Tron issues, etc.) means that USDT payment volumes will far surpass Bitcoin payment volumes on the Lightning Network by this time next year.

He seems much more in the know then I am, so defer to him and others who work on this every day. Seems plausible though. Right now 11 trillion in USDT volumes annually over Tron and the other networks. If only a fraction of that moves to Lightning Network and it already surpasses Bitcoin.

Voltage Cloud is also going all in on Stablecoins, so that tells you something.
