Cryptocurrency payment getaways have the lowest transaction fees so that the business owners gets more profit from it. accepting cryptocurrency as a method of payment opens you to more customers internationally. it will helped your business to increase profitability and revenue growth.
Well, not all crypto coins have low transaction fees, let take for example, Ethereum blockchain have become one of the most expensive blockchains to transact on.
Bitcoin transactions also sometimes, get really expensive most especially, when the it's blockchain network is congested due to high transaction volume on the network.
Making bitcoin a mood of payment in your business can be profitable though, but I think the profitability largely depends on how the business is packaged, if as you are accepting bitcoin payments, the supply/wholeseller who you buy goods from is also accepting bitcoin payment, then this would really be profitable, as you no longer have to worry about how to sell the bitcoin, withdraw to local currency so as to buy the sold goods back.
