I am not speaking about just Bitcoin. I am speaking about every cryptocurrency / token. Regardless of crypto price fluctuations, many online and offline stores are ready to accept crypto as payment. So How will willing are you to spend crypto for your purchases?
If one doesn't spend their crypto for purchases and wait for to spend their crypto when its price is nice, are they really considering it as a cryptocurrency or can we assume like those people are treating more like a security or investment instrument?
When the market get down that means most of the investors will loss by their investment. I think if one is not overwhelmed with big financial problems, then no one will want to sell if the market is down. However, if someone is purchased by crypto currency and is profitable, if he thinks it is good for him to take the profit in this case I think it should be sold. However, there are big differences between investing in other altcoins and Bitcoin. If anyone holds a bitcoin, it is best not to sell it because the price will rise at any time. Which may not be the same with others.
