About the White House plans, any small move toward clearer rules or tax breaks will always cause some reaction in the market. But removing capital gains taxes on Bitcoin completely?...... That is probably just wishful thinking. It would be a huge deal, but honestly, taxes are one of the few tools the government still uses to control crypto. If they make any changes, it will likely be small adjustments, not a full removal.
Too much to hope for but it would likely release a huge load of spending into the economy.
