Exchange to stable coin might be a forward answer to protect from volatility and only trade with some portion of your money to prevent from huge loss. Volatility is the purpose why people are trading with Bitcoin, since they have a chance to made good sum money rather than other trading asset. Made 1% profit each day is already good, don't be too greedy or you could loss.
This is actually a good advice.
Exchanging your BTCs to a stable alternate cryptocurrency may be the key but this would involve some risk associated with its price. Though the only trade back to this exchange is the limited amount of profit one would accumulate on the process.
Still, I do think that HODLing will be the way to go for long-term investments. If a person wants to focus on short-term gains, then there would be some risks also associated due to its price volatility. That is why, the key is always research and knowledge on the market.
I don't think there is actually a receipe how to protect the Bitcoin from volatility. The only thing you can do is to protect yourself from the possible losses caused by this volatility.
One of the possibility could be diversified investments but if you want to make the profit you need to take certain risk.
To my opinion to keep the eye on the market constantly, watching for the trends snd getting knowledge and information about the Bitcoin functioning is one possible way.
