Do they all use the gateway to exchange those for stable coins or do they hold that?
Any company accepting bitcoin as a means of payment must have thought about it, the volatility nature of the market and how it will affect their business if the price of bitcoin keeps depreciating. Big companies that have large inflow of money in and out won’t be affected by the little volatilities we see in the market as it will not have enough impact on their total funds saved in bitcoin.
I am sure they have different strategy on how to still get their profits at the end of the business after collecting payment in bitcoin. This is something that needs an expert to know how to play around with the market and also the crypto market to arrive at a good profit at the end of the day. Collecting bitcoin through exchanges, converting to stable coins and other methods can all be used in their own advantage if they know how to manage it well.
