Anti-competitive against what?Fill a lawsuit and see how that will work as there is nothing about competition or monopoly here.
You don't realize how ridiculous it is, the chant here is always that bitcoin will kill banks, effectively creating a monopoly since there will be only bitcoin and nothing else but at the same time you go enraged when a bank decided who it wants to serve! The same age about CEX, there was no need for all of those in the first place at all, and in a true bitcoin economy there would be no need for it either, the whole thing of being your own bank, no third party, no nothing, but god forbid they would get closed as the pitchforks will be raised and lit.
That thing with the refund is the pure example of zealotism I hate so much.
You buy some coins via a bank transfer you send them to a Ponzi scheme and your bank doesn't offer a refund? The evil bankers!!!
Bitcoin transactions are irreversible? That's how things should be!
Too many acts on impulses on the news and too many think with their wallets, not with their brain.
