The barriers
Whether a company wants to convert from fiat or pay their employees directly out of their bitcoin holdings, it's no simple operation.
Companies looking to boost adoption in this fashion face countless hurdles, not least of which is implementing the procedures themselves.
Whether they want to hold the keys in-house or set it up through a payment processor who does it for them, these things are always fraught with complications.
However, the tax implications are by far the biggest barrier to corporate adoption.
Even before bitcoin was invented, the late great libertarian economist Milton Friedman hypothesized about a peer-to-peer internet cash and spoke to the benefits of people using such a currency to avoid taxes.
Nevertheless, most legitimate businesses do want to ensure that they avoid trouble with the law by keeping a clean book and paying the proper taxes.
I can say from experience that paying one's team members in bitcoin can be particularly difficult. Sending bitcoin is so much easier and cheaper than traditional methods, but reporting on such is not only logistically cumbersome, it's expensive.
Fortunately, some industry participants have been making great headway toward addressing this matter.
