yes, not only focussed on the how much you can gain by invest some money, invest your time and knowledge will arguably much better if you cannot do something useful in bear market (as a trader)
I think that it is a serious issue, I think most of the time people do not know that how much they should invest in trading cryptos, I think that you should make different strategy for different crypto currencies and always tray to invest such amount of money that you can easy bear and which cannot affect you trading in future.
