it is true that we do not need to be discouraged by the very low price of bitcoin like this, because I also believe that the price of bitcoin will return above the peak price in 2017 yesterday.
that can be the only strategy which can prevent us from a big lost. in fact most of the people lose their heart when the price fell down and then stay down for a long time. they want to get rid from the market even if they will lose their money.
