Even so, a 1.6 billion dollar valuation of coinbase is certainly very high. Assuming that over the course of the long term they are comparable to something like intercontinental exchange (the owner of NYSE/EURONEXT, and controller of the clearing house for 50% of the worlds oil futures/derivative products). The total market cap of coins traded on their platform would need to be magnitudes larger to justify this valuation unless they can somehow either continue to justify their high fees amidst competition, or they would need to totally monopolize all future cryptocurrency banking, something that could certainly involve large amounts of competition in the future as well.
