Well, isn't he already supporting cryptos? Preferably Bitcoin, since this is the ones that he always mentioned. As long as he will stick to this, we can surely experience more gains, most especially on those solid coins like Solana, so yeah, obviously that it is better to just HODL them than trading/selling them.

And even if let say there is no election that occurred and Trump or other candidates aren't involved in cryptos, Solana is still worth keeping because the crypto market can still rise on their own, as there are already lots of people who are now into them. Most cryptos are also decentralized, so as long as the person is willing, nothing can stop them engaging from it.
