For about 4 years, I have never done a stop loss. I prefer to stick to that price until I wait for it to rise again. Because I am optimistic that the investment in crypto is for the long term, and of course the market will not always be down, it will definitely rise again. Believe it.
It would have been better that you just keep your coin in the wallet and continue holding it until it grows, because if you are doing this in trading, then you will be practicing long term investment and not trading. A trader takes advantage of every rise and fall within a short period of time which is usually with a day or week to make profit.
More so, someone who is margin trading or leveraging can never do that because if the coin being traded suffers loss of value more than the money he can trade, he will automatically lose the trade which stop loss would have just guard against if he had used it.
