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?
I don't think so, because bitcoin is very difficult to predict and unstable value makes it impossible to accept it as a payment tool, but maybe Amazon will accept it if it is a stable coin.
