In my country, there are schools / institutes where you can pay them with bitcoin. I don't know if the exchange is just converting it to fiat before paying it to the designation of your payment. But with your concern, I don't have an idea if there is a training course or institute that is now accepting bitcoin. And do you mean online training course? or do you mean near in your place? Where do you even live?
Official institutes/schools you mean or independent ones? I have never seen any institute considered official by the country accepting Bitcoins, maybe only independent courses especially online. They can be good too, but worhtless depending where you will work as there are many places that only accept certificates from courses/schools considered legal by the governments.
If you'll read again what I said, I don't really know if those schools or institutes that are supported by that exchange directly paying bitcoins to them or they are converting it first to fiat before transmitting to those schools. If it is not clear to you, it's like this. Bitcoin user > exchange > (fiat/bitcoin) > schools. That's the process that I'm saying for those schools and institutes that accepts bitcoin.
What I mean is that these schools probaly are not considered legit by the country. Legal insitutes can't accept Bitcoin as payment method, imagine how difficult it's for exchanges to set up their businesses on a country, now imagine a school, too much bureaucracy. The schools doing this are probably independent, decentralized I mean...
