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.
The question is how much you bought bitcoin and ethereum? and how many you bought?
The decision is in your hands, you only see the bad days but you'll never see it grow if you consider selling it today. If you consider yourself affected by the fluctuation then you have a weak hands but give it a little more time and see if the market goes well after few weeks.
