I'm not going to sell in the nearest 5 or so years or when I will be in a big need of money. I keep putting money in crypto on monthly basis. Same amount every month, doesn't matter if BTC is at 1000 or 10000$ I'll buy it and store it. As for now speaking I'm over 200% of value put. Not sure if it will keep going up and won't crash. But I invest only as much as I can handle to lose and don't worry about it at all. It's just there in any case.
