Ditto above. Crypto is cool & awesome today - but hard telling what will be the next big thing. Think ahead for the next 20-30 years, not the next 2 years. Get a degree in the underlying tools & concepts under IT and cryptography. Make sure to take a Data Structures class - probably & most useful best class I ever took.
I have long held that 6 months of real-world employment is worth more than a 4 year degree. There's far too many people that have parked in college, think they are awesome, but are totally useless at doing anything but taking classes. You're better off getting out there and doing the job, and taking classes on the side - IMHO.
Getting something to prove your skills with crypto is still in its infancy. There's this cert, but not sure how widely recognized it is:

If you want a good free textbook, the all of "Mastering Bitcoin" is online - best deep dive I have found yet.
