Short term yes, long term no, btc will always have the world's support and soon will be accepted in most countries which means more value and benefits, for short term gain, I can sell some btc to ride the sol hype to be able to make quick gains to buy more btc, for long term goal, btc is key.
in the short term, it might still make sense, because using a token to make your bitcoin or ethereum bigger is a pretty good method, especially if it's short term.
however, I also have the same opinion regarding the long term. to be honest, I probably wouldn't do that short term or long term. I prefer to use the new money for it. For example, if I see the potential for SOL to pump up soon, I'd rather use the money I've earned than sell an asset that I've been holding onto for years. this will make me avoid the risk of correction that occurs on the SOL coin. well, that's just an example. the way to sell bitcoin/ethereum to take advantage of the moment of SOL seems quite risky. it's great if you're on time, but if the price dumps, then it's a waste of time holding bitcoin/ethereum all those years before.
