That was exactly why most of newbie and some trader lose there money simply because they lose the patience when it comes to do trading. I think the best way in trading is invest only that enough to your budjet and dont go all in because if you need some you cant sell your holding tokens and coins in a lower price just to fill your daily expences.
And it is also not possible for novices to not lose their senses during high and prolonged fluctuations. Patience is not that someone can learn without knowledge. Only a person with deep sight of crypto currencies can deal with the changing situations of this world. If a trader has trust in the strength of his coin and believes it to have a good future, no matter how bad market goes, and he will hold his coin.
