How to buy agi tokens as an investment in the singularitynet vision for the future

Hi, I am Jonas. I’d like to invest in the vision of singularityNET but I don’t know how to buy and store the AGI tokens. I have no type of knowledge nor experience in crypto currency but I believe in singularityNET AND I’d like to be part of the family. I already downloaded and created the metamask account but I still don’t understand how to use my fiat bank account or my debit card to buy the AGI tokens. Please help!

Where do you live? Europe, Asia, Afrika,…?
