“Proton is a Swiss company and Swiss companies above a certain size have to undergo what is known as a mandatory legal audit and to get a legal audit done you need to find an auditing company that is willing to run your full audit generally because Proton is a bigger company that is more credible in many ways we try to go with one of the big four accounting firms right so actually it’s public information because it’s on the Geneva registered to Commerce but actually you know we use PWC as our auditor and the thing about big four auditing firms is they are pretty wary of crypto in general and to pass your audit you need to have very good Revenue recognition because it’s something that you have to do properly so already the fact that we accept Bitcoin has made it so that certain Auditors refuse to work with us and the worry that we have is you know if we do Monero that may further limit the Auditors that are willing and able to work with us and at some point you know that poses a problem for us from a legal standpoint because we required to get an audit and we want to get an audit from a reputable firm so it’s yeah I hate to say it right but Monero has a reputational problem that needs to be let’s say separately addressed first before it can gain more widespread acceptance because for a lot of companies there are real business reasons why they are simply unable to do it”
