After 100% vaccination the world might slowly be back to normal. It will start the daily activities, out door trip, and of course the economy growth. And what about Bitcoin? Of course people will have more money and might invest in Bitcoin, but I assume it cannot pump the price aggressively. Bitcoin has its own system and has a team working behind the scenes. Covid 19 has nothing to do to increase or dump Bitcoin price unless done purposely in coincidence way.
