Good stuff but very long to read
So the students, in the majority, used Bitcoin as a store of value. Not really much different than in the crypto community. The real uses were very slow, again not much different. Over 10% converted to fiat because they were not interested (when you look at the lifespan of students' credits for completing their studies, I'm not surprised that they preferred to get the $350 in fiat)
You also have to consider that they're students and likely needed at least a portion of the money they got from cryptos to reduce their expenses or pay for some of them at the very least. A lot of students do not have money to spend on luxury goods, to begin with, let alone money to have invested when it could be used as a ramen fund. Even if they attend MIT, they're probably suffering more from low incomes due to the affluence of their school and the relatively high cost of living that comes with it. $350 is a lot of money for a student, and it can be a month's worth of groceries, maybe two if they eat cheap. Unless they're aware that they have a good job for the summertime or post-graduation, they will likely be extremely financially conservative. The study can be kind of skewed this way; the demographics don't have a wide consideration and thus skims over the people who do treat it as an investment or "new way of life". It is representative of what a lot of people think of cryptos, but not realistic in most cases.
It's a relatively good study to read, and there are some lessons/ideas that can be taken from it, but it must always have the demographics in mind since there are relatively strong biases.
