How can you live like that? Are you constantly watching all the financial news and always sell everything you own at peaks? Your car, your tools...
When you say "you should have sold..." you're making an asumption that is false. You are assuming we are all the same and want the same thing....
There are all sorts of types of players in this game. There are people that purchase items to use but are mostly interested in their value and will try to sell before a crash... but like IRL, they are very few. Most would want to work on their avatar, account, goals for the long run. while peaks like that hurts today's balance, working on long run pays off more and it's more rewarding to focus on building something than stressing over the charts every hour, imo.
It's fine to live for the peak, that gives you a rush and keeps you constantly alert I guess.... but it's also fine to try and perform for the long run. I think most people actually prefer the long term results...
And most valuable assets are usually in the hands of these people, while people chasing peaks end up not being able to touch much valuable stuff because of fear of loosing value, "because 2008" or other experiences.
Probably markets will crash further this year but they will be back up again, even higher, that cannot be avoided. As for our little corner of the world, EU, on top of TWEN and UE5 upcoming booms, we just got news there will be a 3rd boom, NFT thingy which might be of more impact than TWEN and UE5 altogether, from the advertising of the sale alone, not to mention if someone capable gets their hands on one of those full of potential contracts and starts doing some really good recruitment...
