Bitcoin was still on its infancy during that time and this comparison would certainly be in favor of Bitcoin. The traditional assets don't move like that as they're more established and there won't be that much fluctuation anymore except with the real estate. Going on with today's price of Bitcoin and going back to its after a decade, we may have a lesser gain but I think that Bitcoin is still going to be the winner by that time.
As time goes by for Bitcoin, the increase is decreasing and if you've noticed that. From all of the ATHs, you can count how many times it had grown from the former ATH that it has got. So, those that have got in too early like under 2014 were the luckiest but I don't think that many of them are still holding when you have made like 10x-20x, you'd probably sell and that's the main point why many have sold a lot in the past. But as about doing the same mistake again, I wouldn't make the same mistake as I did in the last bull run that even before it, I've sold terribly.
We can't judge people who sold early because we have our own needs. Lucky for you if you have other means to sustain your living. But if you are relying from the profits that you can make out of this market, the likelihood that you will sell of is always there. So it is not about your belief on this market but sometimes it is your financial capability to hold your assets.
