It's not surprising because bitcoin is a decentralized currency and no country would immediately use a currency that they cannot control or could go out of control. As the market price continues to increase it's getting riskier to hold your bitcoin as well because no one really knows what bitcoin could end up but it has a great potential to adopt in some countries or maybe get support from the government making it an asset. We could agree to his opinion as the price continues to go to the moon or if the bitcoin continues to adopt countries might find a way to make bitcoin a centralized currency we never know what could happen if they want to adapt.
