The business owners will get the most benefits of accepting BTC,when they start using it to purchase goods and services from other businesses.Bitcoin should become a business-to-business currency,also known as B2B.Getting adopted by B2C companies (or business-to-customer) is also great,but the companies will eventually have to convert the BTC into fiat,which kinda makes the whole BTC adoption process pointless.
Lol unless the company is willing to keep the Bitcoin on hold then yeah they will benefits but if they will circulate the coin and then the value in fiat drops hard then how can they afford to sustain their purchasing power that surely now all are using crypto to purchase.
this will only applicable in some but not at all and this is the problem of the companies that is why not all are willing to accept bitcoin because the Volatility is what will affect their system.
Also bear in mind that if the company is using a 3rd party due to not having their own node, then theres no decentralization in that. That aside, companies accepting Bitcoin as payment system will ease the burden of charges and easy tracking of transactions
+1 here mate.
