I know sooner than later more people will understand how crypto currency works and accept bitcoin as a means of exchange of goods and services in their daily dealings. In my candid opinion, It does not matter who hodl or sells bitcoin. In order to uphold the value bitcoin deserves, we need to use it in our daily activities, such as making payments to friends and business partners who are into crypto, this is the best form of advertisement of crypto. When this value is placed on bitcoin, many of us would no longer worry who sells or hodl, just as it is in the case of fiat currency.
No it does not matter who sells or holds. Do not mind others business, just focus on your starategy in life. Well there are some people at these days who are already accepting bitcoin as exchange to their goods. But i think if crypto is already accepted by everybody, many people especially traders will still hold cryptos because it is one way to earn more profit.
