The problem with the integration of cryptocurrency in small business is that most entrepreneurs are faced with the fact that they need to pay taxes, and given that in most countries there are no prescribed rules that would regulate taxation, trade and exchange for Fiat. In addition, the volatility of cryptocurrencies scares many business representatives, but they can use services with instant conversion of cryptocurrency, for example, into stablecoin USDT and thus the volatility is reduced to zero and the business does not lose money on this.
