I wouldn't sell any imo. if anything his conviction should have grown. sell now for what? to buy back higher in 4 years? diversifying in assets that historically perform worse would not make me sleep better tbh esp considering the events on the horizon for btc... nation states buying, US strategic reserve potential, microstrategy issuing 10b stock proposal, etf's buying at an alarming rate. Way too much happening imo to sell at the precipice of what very well could be the end of consumer friendly pricing for btc.
If you’re right that Bitcoin will go up forever, there is no need to buy any back because when Bitcoin goes up, it becomes a larger part of your portfolio. To rebalance your portfolio (get back to the same percentage), you need to sell, and there’s never a time to buy unless it goes down again.
But going by the price history, Bitcoin is very volatile, going down as well as up. Keeping it a fixed percentage of your portfolio would result in buying when it’s lower.
(Also, Congress just showed that many Republicans won’t listen to Trump, or Musk, when they have other ideas.)
