I believe that most business owners will prefer to transact money transfers with their customers directly without using an exchange, that will be a third party, and you'll have to pay this third party or middle man money for his services, whether you like it or not.
In cryptocurrency, we have many ways to safely resist ay third party influence in what we do as long as we have the knowledge on how to go about it, bitcoin is not what we can just assume to be thesame as the way we treat other cryptocurrencies which are centralized, using bitcoin privately begin with the kind of wallet we use, many people will create a crypto account and take that as wallet from the exchanges they use, while some will rely on other people in helping them through what they would have learnt to know by themselves.
I think that for a person who uses bitcoin the best thing to do is to make these exchanges by himself, without the need for help from a third party, because I consider that this would be a bit counterproductive for said individual. It is true that these platforms provide very striking features, but there is no way to avoid this type of method, for the simple fact that it might not be as safe as you think, although I am also clear that if you are not knowledgeable or skilled in doing it on your own, You could choose this other option yourself, that is, it could be taken as plan B. In any case, they are not bad, and as all services of this type have their risk, so it is best to use something with which you feel comfortable, and Of course, they have a decent reputation to avoid bad times, without lowering their guard, since a failure can exist at any moment... so, in conclusion, the use of an intermediary is based on choice and how the person feels with said platform.
We do prefer this way but are you that willing on making that p2p transactions with other people personally or would be going direct exchange online with other people? You are really that prone on getting scammed
plus we know that in speaking about convenience then these platforms or 3rd party do really give out that kind of services which gives out that good user experience which is something that less hassle.
Plus, not all platforms does require KYC (for now) on making out these kind of transactions which is related to fiat specially on having that conversion of your crypto to fiat, for some which before you could be
able to make out some p2p transactions which it would really be that requiring that kind of verification first before you can proceed.
Regulation and centralization is something that would really be inevitable in speaking about services that being offered and as long it is really that attached into some other centralized services
then it would be no shocking that they would really be touching up that regulation aspect.
