What would continue to drive the market up higher from here? Serious question.
What always did.
Bitcoin is an excellent store of value. Can't be confiscated. There are 16,4 million bitcoins currently in circulation. There will be only 21 million. There are more than 7 billion humans on this planet. Central banks are printing new money in hundreds of billions every month. This is more than enough to drive bitcoin price to really insane levels.
