I have bought bitcoin and ethereum, in the next few days, I have seen worse market prices every day, do I have to cut my losses or I have to wait patiently, what I do.
You should hold and that is the best advice. Because the price of Bitcoin is currently very cheap and you should invest more instead of fearing. In addition, you should revise your investment strategy and thinking. If investing only brings feelings of anxiety to you, then you are failing.
