I have noticed to my college student neighbor, when he get big reward from the airdrop he eat to the expensive restaurant and spend his money to the things that did not needed most. This 2018 he did not receive big reward from airdrop and he realize that he need to save money for his studies and for his future.
I personally do not think that bitcoin may have any use for the college students, In fact bitcoin is currently use as for investment and trading purposes, while the college students have to fulfill their education first and when they become from their college and stud, then they should take active part in trading and investment.
