What do you think, how many people are ready to sell their goods or services on crypto? Let's say that we have service which help quick and easy to build online store and sell for cryptocurrency. What kind of reasons can motivate people to start a crypto business?
If I had a store, I would have applied for payments in cryptocurrency. Because the cost of buying crypto in decentralized exchanges is very expensive and it can cost you more than 3% to buy it and it takes a lot of time.
But for this to happen broadly is difficult because many services are still not accepting crypto now and holding it is also a disadvantage. Instead of holding it, we can hold fiat money and deposit it and still earn interest every year. That's why many businesses have yet to push for holding cryptocurrencies.
