I discovered that Bitcoin has destroyed the rule of the third party.
And yet, many businesses use custodial wallets (such as Coinbase) to receive bitcoin payments. Even if it's not mandatory, anymore, to use an intermediary for online transactions, we observe that most of the users haven't acknowledged its importance. We still see a significant number of merchants and customers who don't want to be responsible for their own money.
Yeah, it's the “ultimate” access, but what will make people respect that?
Most of them use payment processors such as Bitpay and Coinbase and most of them don't actually receive any bitcoins but they receive the fiat equivalent of it. In other words the reasons why they do it is not because they want someone else to control their money but because they want to receive fiat not bitcoin which is because of its volatile price and the fear they have of sudden dumps.
