should I be worried?
If you own a lot of some 2.0 coin that's dependent on US businesses for asset/share issuance on that coin's platform, or if you work for or own one of these companies, then, yeah, maybe be a little worried.
If you're just holding bitcoin, then just watch as the benefits of actual decentralization and trustlessness become more apparent (over the longer-term) to the previously wide-eyed and naive "Bitcoin 2.0" crowd.
