I have a question:
What is the best strategy when you reach to STOP level in trading?
1) Stop buying?
2) Selling?
With such a volatile market like cryptocurrencies I don't really recommend you to have stop limits on your trades. I think you must have an exit strategy, both for taking profits and taking losses, but to have automatic exit points could be dangerous. Sometimes the spikes ate so big, that will trigger your stoploss and you wouldn't even be in any danger if you kept your trade open. I heard that sometimes, the variation is so big, that your stop loss doesn't even get triggered. So on both situation you might be guaranteed a loss, so I think it's better to not use a stop limit at all, and you should just do everything manually.
