Security audit
I go through how you currently hold your bitcoin, identify where it is vulnerable, and tell you what to change and in what order. You pay €300 in advance. That covers a standard setup and for most people it is the whole cost. If yours is more complicated, I scope it with you and quote the difference before I start any of the extra work, up to around €1000 at the top end.
About this product
An audit is me looking at your actual setup, not a generic checklist. I identify the vulnerabilities in how you store your bitcoin and give you recommendations you can act on, ordered by what matters most.
What the €300 buys
The €300 is an advance, paid when you order. It covers the baseline audit: I review the setup you describe, work through it with you, and come back with what I found and what I would change.
For a standard setup that is the entire price. There is no second invoice and nothing further to pay.
When it costs more
Some setups are not standard. More devices, more keys, more people involved, more moving parts, all of it takes more of my time. When that is the case I tell you before I do the work, not after.
We have a scoping conversation, I give you a number, and you decide whether to go ahead. A genuinely complex setup lands at around €1000 at the top end. If you would rather stop at the baseline, we stop at the baseline and you keep the findings from it.
You will never get an invoice from me that you did not agree to first.
