Thank you for the response; I'm more interested in the owners of these companies - how do they withdraw their earned crypto on the platform since they can't directly withdraw it to a bank? Let's say platform X has earned a certain amount of money (crypto) from cryptocurrency exchange services and would like to realize their profits, but the company doesn't have its own bank account, so how do the owners pay themselves, for example, profits or salaries? In addition to their profits, they have to pay their employees, blockchain developers, cover server maintenance costs in fiat currency, and so on. So, how do they convert the crypto earned through the platform into fiat and how do they withdraw it for themselves?
If the company not has the own Bank you can use third party way selling bitcoin fund by P2P transaction, but I don't see available with fund based on company how to verify with exchange account. For paying employer service seems sending trough wallet still available but if your decision want to withdraw become cash money through the bank seems difficult if your business not linked as personal account.
Need to build one trusted account and withdraw from business wallet to exchange account but with personal or individual account registering, maybe use third party is the last option way but difficult to see who has most trusted side for withdrawing funds of cryptocurrency wallet to be fiat or cash money.
