Despite Elon, this price will increase. Big companies haven't invested unnecessarily in bitcoin. That's why I am very hopeful. I think we can see 150 thousand dollars by the end of this year.
Soon everyone will forget about elon tweet and any good news can instantly pump the bitcoin price.
If tesla does not accepts bitcoin payment, it won't be matter much when other companies start adopting bitcoin. Soon tesla will be force to change thier decision also.
