The only safe haven in cryptocurrency is the stable coin like USDT, I personally purchased more Bitcoin few days ago because I still believe that the value would increase before long and I'm already in profit as at now. My safe haven in this space is with Bitcoin and USDT.
If you want to hold crypto and you want to feel safe, USDT is one of many options for the stable coins. If you have USDT, you don't have to worry from the up and down of the price because USDT does not get too big of the impact so you can buy another coin if the price of them is down too deep. But you cannot expect to make a profit, especially for a big profit from USDT because the price will not increase so high like the other coins. So you will need to buy another coin if you want to make a profit.
