I get where you're coming from, but not declaring profits would only make things worse in the long run. It's tempting to think that avoiding taxes altogether might be the solution, but the reality is that the consequences of doing so can be far more devastating.
I do wonder sometimes if we'd be better off with a system where taxes were optional or at least more transparent — where you could choose to allocate your taxes to specific things and opt out of others. There are many areas I would gladly contribute to, but others come off as less justifiable.
Unfortunately, we're stuck in a system where taxes, especially with crypto, are rather unpredictable and burdensome. I guess the key is to push for better regulations and more reasonable tax policies rather than avoid them altogether.
