What database to choose for the project?

Question

Database

The startup I'm involved with is an automated investment platform that helps Nigerians/Africans invest their earnings. The inn-vest app debits your pre-registered bank account at regular intervals (weekly, monthly, or quarterly) and automatically places the money in a crypto wallet, or buys an option, stock, or US dollar, depending on the user's choice.
We have a problem in choosing a database. What database do companies that work with crypto usually use?

Answer 1

crypto is not a criterion for choosing a database, the criterion is the tasks themselves, or the presence of a specialist who knows how to use a specific database.

Answer 2

what difference does it make what you know and take it. mysql will do just fine.
Moreover, the chances of taking off for such projects are usually equal to zero.
especially when they are made by people who do not know what base to take.
so there will be no problems with loading the database
