Another burden that they would have to face would be trusting an exchange to convert the tuition payment into local currency quickly without paying much fee and trusting that the exchanges have good security measures in place as well.
I'm not saying I don't agree with Universities accepting crypto for tuition, but I believe that they have many downsides to doing so which will prevent many universities all over the world from doing this.
Your point of view is actually as good as mine. In as much as many organizations, businesses, and individuals would want to accept or spend Bitcoin, the hurdle therein is still how to overcome the highly volatile nature of bitcoin and other crypto assets. Except those who are well informed in Fintech, forex, and crypto, it will be very hard to believe crypto.
