Considering the difficulty involved in even buying bitcoin I'd have to say no. If you want to make a sizeable investment you need to hand over large amounts of personal data to an exchange. I'm talking the works; routing number, passport, proof of residency etc. I should be able to simply walk to a BTC ATM put cash in and add it to a wallet on my phone (perhaps you can in some places?). Additionally, exchanges like Coinbase are required to report any transaction over 20,000USD to the IRS. Fiat cash is much less of a PITA.
