In every country, there is an available bank that you can send more $50,000 in one transaction. Just say, you never had that amount in your account or you have not upgraded your account. Currently, I can spend $25,000 in a day using fiat. And I will send through my local bank app, even though I dont have such amount in my account, I have a large transaction limit.
Which bank is that? From your username, I guess you are from Nigeria. No local bank can let you spend up to $25000 a month. Although, maybe you might be able to do that with Fintech like the unrecommended Chipper Cash. The recent one that I know is that you can only spend up to $1000 in a month or so quarterly but it also varies from customers to customers. Before, the naira master card can not be used for international payments since 2022.
