checkout bitwage or uphold, those should do the trick
I have never thought this type of services also exist. But how they regulate that tax thing or they are not regulate by government? Quite complex to understand how they are able to do that.
I would personally think it's a way of avoiding taxes. Maybe it's some kind of system that takes your net income per paycheck and takes the percentage you want in Bitcoin out and then automatically buys Bitcoin at some exchange site like Xapo, Circle, or coinbase and sends it to your wallet. Too much hassle IMO, when you can easily just deposit the check into your bank account and buy it manually. I even think Circle or Coinbase gives you that option to automatically buy X amount in dollars every week, 2 weeks, etc based on what you want to spend.
So pretty pointless service though... At least it is to me.
