Selling Advice

So I bought some Bitcoin in like 2016. They were $200 roughly and I bought like 1.2. It crashed and I didn’t understand crypto and it told me I had like $40 in there and I needed $50 to pull out. So I licked my wounds and forgot about it. 5 years later it was worth a little over $50,000. When it crashed again to like $17,000 I converted my savings of $13000 and kept investing. Now I have a little more than 3 coins after about 2 years. Now it says I’m just under 120k. My question is because I don’t need the money as I make just, and I mean just enough to live with $500 savings every month if nothing happens, and a stable guaranteed job for the next 5 years. Should I leave it or sell it? If I lose the money I will just stay with my job longer, but with taxes pulling it out won’t change my life or retire me. Probably just be about a new tesla. Should I trust it will go up and keep investing? I have about 20k in regular stable stocks and less than 5k in other crypto. I don’t understand taxes that well, I know there’s Capital Gains and income. I don’t know if it is worth it.
