One of the principal challenges with crypto, including BTC, are the
boom or bust cycles. This will become less of an issue as the broader crypto industry, as well as applicable regulatory frameworks mature to a "sufficient level." However, that might not be for a while, if ever given the decentralized nature of the most prominent blockchains.
In other words, the ongoing embrace of BTC by nation states like El Salvador and Bhutan — in particular given the relative size and existing vulnerabilities of some of these
crypto crazy countries' economies — will grant hostile state or even
new and exploitable vulnerabilities for destabilizing, if not outright crashing and/or
couping these countries' economies and governments, respectively, especially if threat actors are positioned to time and aggravate, never mind instigate a market crisis.
Upcoming, if not recent Trumpian missteps in embracing crypto — especially should they start escalating in severity and increasing in frequency — will inevitably create and expose new attack surfaces for Chinese, Russian, British, Israeli and/or even North Korean threat actors to "fuck with."
