What do you think Bitcoins biggest vulnerability is?
I think there are two major vulnerabilities with bitcoin which are volatility and decentralization yet are what makes bitcoin sweet. without bitcoin price volatility and decentralization in nature, the governments around the world would never have an issue with bitcoin.
Bitcoin and crypto have this popularity because of the volatility effect of its price. It isn't surprising how it gains popularity pretty easy cause a lot of big investors have been involved in this growing market. Such vulnerabilities will remain until crypto isn't over and it much more volatile as I think if it was supported globally.
