I think small business owners are not educated enough about cryptocurrency and that is the main reason why crypto is not widely used in the small business sector. Actually, implementing crypto as a payment method is very easy and we all need to teach small business owners if we want to help cryptocurrency expand.
The main thing is education about cryptocurrency to small entrepreneurs, that by accepting cryptocurrency payments, the opportunity to increase turnover means increasing profits. Small entrepreneurs in tourist areas allow payment using cryptocurrency, with the state's record legalizing it.
