In fact, the only way out is trading. You can constantly buy and sell them, so you can also make money.
I don't think trading is a way to protect our Bitcoin from volatility. The volatility is the nature of Bitcoin. Although we trade Bitcoin, we cannot avoid the fact the price is always fluctuating. In my opinion, there is no way to avoid the volatility, it is impossible. What we should do is finding a way to deal with the volatility. Buying when the Bitcoin price decreases, then sell the Bitcoin when it reaches our target in selling. It is a simple way to deal with volatility.
That's right imo.
But I think that what @zaesvlas wants to say is about the way to cover or face the volatility, So we can only utilize the volatility of the market by doing trading, convert it to USDT, and then trading it again.
We know that market volatility cannot be ignored and so far, the volatility is very high, not only on Bitcoin but also for other altcoins.
if we want a stable portfolio, we need to convert only to stable coins.
But of course, this may be not giving you big profits, different from when we are trading non-stable coins.
Btw, one of the worst things that we do to face market volatility may be panic, if we are panic about the market volatility and we sell them every time the price drops, we can lose more and more money.
