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 think they are not that stupid to make such a decision, they know that this bitcoin is very volatile so they might avoid it. We ourselves have seen all investors who are now somehow reported to have bought at its ATH and then compared to the current situation. I don't think Amazon will take that risk.
They will not play short and will not take long-term risks
