All courses will be bought using BDG. However students can pay directly in fiat and the platform will automatically change that fiat into BDG using available exchanges.
In the first release that is planned soon users will need to buy BDG on their own, but with the next release the platform will take fiat and transform it.
But where is the advancement of using blockchain?! There is no need for a blockchain and the product is not better with a blockchain!
