To a certain extent, I agree. Though, crypto isn’t at the point of being a “common currency” as no one is willing to spend it on everyday products/services.
So yes, it’s an important step in the crypto space but IMO, it’s one we’re still far off from requiring.
As for other exchanges, I agree as Coinbase only trades 4 coins currently yet is the largest most commonly used. SO MANY people are still in the side lines waiting for ease and convenience to come to the market. With ease and convenience, mass adoption will be expedited, then the need for this sort of thing will be relevant.
