HOLD is not the only trading strategy, but I think it takes courage to invest in cryptocurrencies. Due to certain news or market changes, we are not free to sell crypto.
I guess it's not courage but patience because we cannot hold for a long time if we don't have patience. It's happened with many people who said they could be patient for a while, but suddenly, when they see the price is falling too deep, they lose their mind and decide to sell their coins. So be careful when you still hold the coin, make sure you have the patience to wait for the price and don't let the bad news ruin your strategy in keeping the coins.
