2- Should assets be sold or held?
There's no definite answer to your question because there's no one that can give a response that they're 100% sure of because all they'll be doing is speculations.
The market can rise or crash, it doesn't really matter as irrespective of what happens you shouldn't be move but continue hodling. Don't sell to avoid the crash, the crash isn't the end of Bitcoin but a distraction to shake out the weak links.
American government are already bullish on Bitcoin and the industry since Trump won the last election. Although I'm not in support with the way the government have gone around their being positive by launching a memecoins (although I don't believe it's the president doing this instead people around him that wants to take advantage of the hype to make money).
The Chinese I don't know about but I know they aren't as bearish as they used to be. Assets should be bought and the target shouldn't be to sell tomorrow but later in the coming years.
