I guess my mind can’t take investing in crypto/stocks

It's been quite a while I've been trying to invest in something, because whenever I have accumulated money, I end up spending in unnecessary stuff (like an extremely overpriced 3090). Thought about trying stocks, but it felt a little complicated to start.

Since crypto seemed easier, high profits were possible and there were even tutorials on how to mine, I thought I should just try.

Other than mining, for the last week I bought around 400$ (45,000 yen) split in Bitcoin, Ether, and Raven, with the mindset of buying it, forgetting about it, and checking in a few years. However, the moment I bought them, I started checking graphs and sites and forums to see how everything is going. It got even worse with the recent crash, I've been spending so much time and mental energy on something I have zero control over.

And this is considering it was just 400$ (well, 310$ now…). If I had bought more, I think my mind would be even more troubled.

In short, I think these volatile markets like crypto and stocks are too much for my anxiety-filled brain. I won't sell any of the crypto I bought, since I considered them gamble money and if I lose it, I lose it. But I think I won't be buying anything anymore, and I'll probably keep mining only when the weather is cool so I don't force my gpu too much (which should take a while, since we're just starting summer)

I think I'll look for some some risk/low return investments instead. My mind will thank me for it.
