Volatility is an integral part of the Bitcoin market. You asked a question, is it possible to avoid volatility? The answer is yes, it is possible. Consider that you have a discretionary income stream coming in every week and you want to accumulate Bitcoin from it. This is the only way to reduce your mental volatility. If I explain it to you a little more clearly maybe you will be able to understand it better. If you consistently accumulate Bitcoin in the DCA method it will not only grow your portfolio but also gain extensive experience in the market due to the long term nature of the market as the price of Bitcoin is volatile and you continue to hold Bitcoin without any stress. When you are continuing to create holding you will be able to create a investment defence wall regardless of market volatility and your financial strength will continue to grow over time.
It seems like you are a bit confused here, am talking of the highlighted statement in your write up, because to the best of my knowledge, volatility is one of the nature of Bitcoin, so is their anyway to avoid it completely? No.
Their is no point getting worked up about volatility because it's part and parcel of bitcoin, so the ideal thing to do is to keep on buying Bitcoin consistently either weekly or monthly, because this current price of Bitcoin is no where near the price it might rise up to in the future, so why disturbing yourself about volatility when the price is till cheap now regardless of how volatile the market is?
Just try am accumulate a huge of bitcoin and hold, because in the future you will be very happy with yourself that you take action now that it's still very cheap.
