I do say it to some of my confidants closer to me that the most delicate aspect of bitcoin is trading, because you can be losing even when we are on bullrun as you take a short position and same can happen to you if you are on long position and the market is falling, this is why we keep hearing about the liquidation worth of assets people are losing each time the market falls or rises, i hope we are always prepared for this, except we are long time investors ready to hodl.
I think it only happens in futures trading where you can lose assets in an instant if you go long/short, the market price is very volatile, it has a very big risk if you do futures trading but with high rewards, it is different if you do spot trading, your assets will remain intact even if the market is down, you just wait for the price to return to normal to sell it or you can sell it at a loss, but that is better than losing all your assets.
