Oh did you mean “are they allowed to do that?” I’ll let them worry about that for their side of things. Strike has been doing it for years as well. The bitcoin lightning network in this case, instead of banks or card processors, is being used to settle the transaction. How the recipient receives it, whether as USD, Bitcoin, or some other currency, is up to their receiving wallet or institution, and probably up to them to track and report as needed. No need to beg for more regulation if it isn’t there. Technology advances far faster that regulators. Always been that way. They’ll catch up eventually.
