Only skipped through the video. Do not sell any coin right now if you believe in the coin in the long term. These bearish times are not easy/fun to look at. I know. But you have to be strong and keep holding/hodling, my friend. Since months it is time to buy coins, not to get rid of it - at least if you are on for the long term.
Anyway, I absolutely understand you. Shut down your nodes if they do not bring you money. Avoid losing money.
