I would have to agree with most of this post . Anytime more buyers are introduced it is a good thing . However in response to the issue with coinbase being expensive I would disagree only because coinbase and gdax should be close to the same thing in anyone's mind who would care to know especially anyone planning on spending 20k. Let's face it trading on the gdax is essentially free and is as simple as can be. Not to mention the ability to switch back and forth with coinbase instantly . Add to that one can load cash directly to ones gdax account for nothing. Oh and let's not forget that when withdrawing , one can withdraw to any account for free, not just a coinbase account. This last feature makes it possible to exchange Bitcoin litecoin or ethereum with anyone with no fees from miners.
