It can not be controlled but can be regulated by government and their institutions but unfortunately, government wants to regulate it the wrong way and they're likely to lose the power to regulate it in the future if they don't want to do it amicably. Although, I agree with you that investing in bitcoin at the right time should be considered as a luck but saying that bitcoin remains strong even during global economic turmoil is where I disagree with you.
The fact that bitcoin normally bounces back after negative trends does not mean it is not being affected by global economic crisis. In fact, the fluctuation of bitcoin price is mostly fuel by global economic issues either positively or negatively.
Regulation is already in place, and should be a vital part of the future of bitcoin. USA for example is the biggest economy in the world, and they regulate it, and allowed it, so much so that the president himself has his own scam coin, which goes to show you that it's a pro-crypto nation but still some stuff are not allowed.
Like you can't go without KYC and hope it works, or use Monero and try to hide your money and hope they would be fine wit hit. There are always limits, what you can do and can't do, they can't "stop" you from doing it, but they can punish you for doing it, that's how it works. Same as almost any other crime, you can steal, kill, evade taxes, etc etc, they won't be able to stop you most of the time, but punish you after you did it.
