Fiat Cashu

That would be a particularly weird place to see them. Lightning I sort of get -- if you're going to use stablecoins, at LEAST don't compound it by using them on Tron or Ethereum (or even Liquid). Ideally, use bitcoin. If the volatility is too much to stomach, and the risk profile of your local fiat is worse than stablecoins...you have my sympathy. Don't delude yourself into thinking its a good idea, but I'd not stand in the way of the tools being rolled out to use it with.
