But the truth is Bitcoin adoption as of now not as a means of payment, Bitcoin adoption is storing the value that holders can make a profit in a certain time.
I doubt this becomes crucial now, when those big holders drop their bags and sell all their Bitcoin have, it will surely have an impact on the market which dropping the price.
However, the awareness has continued to spread and there are some stores now accepting Bitcoin, recently the US added more Bitcoin ATMs which means the demand of the buyers has been there. So I expect that there are massive Bitcoin adoption in the future, in fact, we have a few countries has been starting Bitcoin makes a legal tender.
Right now, we can't expect a lot of merchants accepting bitcoin in their payment method.
However, the numbers are increasing already. But for some holders, they won't spend their satoshis but instead hold it.
It is true, most of btc holders are treating this as investment, where they can exchange it with good profits in the future.
But if there will be merchants available, some of these crypto users will use their services, mostly for convenience purposes.
