It will take a very long time before all businesses in the world begins to make use of the cryptocurrency medium of payment or exchange because most people do not believe in the cryptocurrency as a legitimate or genuine means of payment.
Give and take I will say in the next ten to fifteen years or thereabout. Because I know it is really going to take some time before the government of most countries will give the go ahead to use the cryptocurrency along side Fiat
In my opinion, it will be a matter of a few years from now, my friend.
I see that in the world it is now already possible to pay in Bitcoin, such as airline tickets and hotel rooms.
A lot of businesses are already using crypto currencies, including big names such as Telsa. Even though Tesla has halted bitcoin payment for its car, in the past you could buy cars with bitcoin.
Everything take a time same with crypto. Major firms are testing it's usage now and it has been successful so far. The only issue it'sfacing now is it's volatile nature. Once it's solved,crypto will be embraced by all and sundry.
It will not be possible for every business and institution to adopt cryptocurrency because of its volatile nature. The price of cryptocurrency can decrease rapidly and can tight down a huge capital meant for business.
