If more business people are willing to collect payments in Bitcoin, and more Bitcoin holders are willing to pay with Bitcoin, then the adoption will grow very fast. But these reasons that I mentioned are some of the disadvantages to the adoption as a digital cash for payments. An example is the Nigerian government's unfriendliness towards crypto transactions. What are your thoughts?
If you search for countries that have the most investors of Bitcoin, you will notice that Nigeria is amonge the country that is recognized to have majority of citizens with crypto knowledge and investors.
So, if you are referring to only Nigeria base on this your title, "Re: Bitcoin adoption can grow faster if it is used more as digital cash for payment" Then I think you are wrong because the country has a significant number of people who are investors of Bitcoin or other altcoins, while those who doesn't also have money to invest are engaged with different airdrops to earn free crypto.
Despite the fact that Bitcoin is not a legal tender in Nigeria, I am aware that adoption and wide spread of Bitcoin knowledge in the country is quite astonishing and even better than so many other countries. I even read on this frum that there used to be a Bitcoin ATM in one of the states but it's no more.
For now, for Bitcoin to be accepted for payments legally, it has to work with our local Fiat banks or should I say the CBN of our country so as there would be a balance in the economy and in the administrative offices as a whole.
Even though the knowledge and skill to trade and transact with Bitcoin is more rampant in our society today, the government would have to finally agree first before it can be used openly without police and financial agencies hassling either the business owner or the individual who is caught trading P2p or using it to make payments for goods or services rendered and received.
