It's a very tricky thing @trading. If your in experienced, you never can fully tell how long you are to hold a loosing position on a trade. There is a technic and it should be in your setting of stop loss margin and the same applies to take profit margin. No one likes loosing and as such, you tend to hold a losing position with hope that it would turn back in profit. Eventually, it just might not and you end up losing more than you can afford to lose.
Always put your stop loss just before the previous lower low at the support level and take profit close to the higher high at the resistance level. Once these places are broken, it signifies a possible break out so, you've just got to love the trade before you make the mistake of losing more than you could bare.
Indeed, stop-loss is a good idea for those who can't tolerate losses in trading for a long period.
We know that bitcoin and some altcoins be able to recover and reach the ath again someday, but most of the altcoins can't survive in the market, so it is better to sell those coins rather than hold it for long term in hope it will rise again.
