I think the most secure trading is to use some money from trading capital and use money that will not be in use for the near future,
for example I have $ 1000 and I need to use the money for my family's living needs, then I can use $ 250 for trading and the rest to survive, do you mean from this revelation?
this method is used so that you are not too depressed if the money you have stuck in the expensive price.
People,become vigilant in terms of surviving in this struggle situation of crypto,but in my own thought the best way of surviving is to cut into two some of your capital and used the other half for short term method in trading investment while the other half save it into for holding,so that when there is bullish run,its will be profitable and usable in times of necessity.
