Nothing as far as I can tell, from my checking account to coinbase is a free transfer. No place did they say that by doing this are you going to get a better rate, or if they did say it I missed it.
If I'm not mistaken, Coinbase rates are always a bit lower than a regular (or maybe I should say unregulated) exchange. So maybe there's no fee for the "buy" but the actual exchange rate is not as good.
I actually don't know any Coinbase users to confirm though, as it's only for US people (although a few years back they allowed me to open an account and then had it deleted).
What happened to those services that supposedly allowed you to get your paycheck converted to Bitcoin regularly and links with your salary?
The only one that I could recall off the top of my head is "
BitWage" and judging by most of the recent comments that it has received, it appears that it no longer offers a good/reliable service
[e.g. delays and etc...]!
That's very sad to learn but yes now you mention it this was the one I heard a lot about before. If everyone could implement this easily, even better and that's direct to your wallet rather than to an exchange. But if that's problematic now maybe in the end it needs a professional exchange to handle this directly.
