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.
A good idea, this idea also includes one of the household financial planning strategies. What matters our lifestyle doesn't exceed our, true abilities. From the outside it might look great but from inside suffer. Therefore we have to live realistically and not be lulled by prestige. Although it seems not easy/difficult to control for those who are not familiar, I'm sure slowly it will be more controlled.
