70% my asset has gone.
Did you sell all your coins already?
If not, then this loss may be temporary one because once the market starts moving up then you can start recovering from this losses. If you want to recover back your losses faster then it is the best time to start buying some more coins to average down your price.
People who dont sell or lose all their coins shouldnt worry about their loss because this loss is a temporary loss and as you said that when the market of bitcoin will rise, he will easily recover all his loss in no time. The thing here about which one should be worried is that what will that person do next who has lost or sold out all his btcs because he would not be having a chance on his side to stay in market and he would be having regrets when the process will rise again.
Yes, I wonder why anyone will be losing 70% of their asset in book and decide to turn it physical. As long as they are still there, the market will recover and then the 70% decrease can just turn to 500% increase within few months, so I really do not see any fuss about that.
As long as you did not borrow money from anyone, they are yours and you understood the volatility, then you are fine. However, with respect to how the market affected my gambling, I will say nothing has changed.
