So true big gains comes with big losses because the more you gain the more chances you lose. thats why we need to analyze sometimes we need to see if these is good or bad when you gain more, but in the end if your gain becomes a successful then why would you gain more.
and if we can learning about how to prevent the losses, I think we can avoid big losses although it is always there besides us. the big gains will come to us and we have the option to reduces the losses if we can use the opportunity so we don't have to get the loss. I think if we can gain something, it's time for us to say it is enough for us and don't try to get more than that because our chances to get lost will become big so avoid this.
to avoid loses you should be patient because when the price decreases you hold your coins and do not think of selling no matter how much time passes. If you are impatient then you will lose your money if cannot hold coins for more time. But this is wrong that big earnings is with big loses. It is absolutely nonsense. Nobody wants to lose his money for earning big.
