The difference is of course there.
• The B2B system as far as I know the method of service or product they use uses other parties, but if you are a business you work internationally in conducting transactions or transferring coins, B2B is certainly a good choice, B2B features are more focused on the payment method platform to consumers.
• B2C system without other parties, meaning: You can directly make transactions with consumers.
This B2C method is often used, such as: food business or the like on a large scale.
Of the two methods above, B2B and B2C, of course you can conclude which one is the best to use in the product business, you can use the two payment features depending on the business you are running.
our most challenge is that our resources are limited so we have to start with an MVP just to introduce ourselves to the market, we can't cover both B2C and B2B so we have to choose one and after that choose a specific niche, and this is very important for us to validate this niche, any idea would be appreciated
