I want to buy bitcoin via sepa invoice or sepa direct credit system. Please give me a reliable site, thank you
I can suggest Bitcoin Store HR, based in Croatia, which is a legitimate company (Digital Assets d.o.o.) and has been operating for years. There is a fee of 2-5% depending on which type of cryptocurrency you are buying. It accepts SEPA transfers and is available to European customers.
Another option from Croatia is bitcoin-mjenjacnica.hr, which comes from the company Electrocoin d.o.o. I have personally used both platforms multiple times, and everything went smoothly every time.
