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?
When this technology develops a little more, I think many world-wide companies will accept payments with Bitcoin. Although Amazon is a mediator by bringing the buyer and the seller together, it does not have the chance to return with Bitcoin in a possible situation. So, unfortunately, the money sent to a defective product, faulty product sale or fraud cannot be retrieved again and this can cause big problems for both buyers and sellers. Therefore, I think that such a situation will not happen again in the near future, but in the near future such a situation is likely to occur.
