There are a lot of small shops which accept crypto payments around the world. However, in my opinion, what will really push the cryptocurrencies forward is the adoption of Bitcoin by some big player in the trading industry, such as Amazon.
What do you think, will Amazon start to accept Bitcoin as a payment method if its price rises to new-record values again (like in 2017)? Could it be that they are not adopting it because they treat crypto as a hostile technology for their business? Or they just don't take Bitcoin seriously, like thinking it will despair in the near future?
You imagine you have a lot of billion-dollar company, and your billions are always in operation and in circulation, and here you start working with bitcoin, you will not be able to receive bitcoins from customers and immediately translate them into dollars on the exchange, of course not. And here you have by the end of the year gathered bitcoins 300 million, and the price of bitcoin as collapsed to the bottom and you have 300 000 dollars left. The question will you work with bitcoin??? Of course not.
