Contact CoinVac
Found a bug in a calculator, spotted something wrong in a guide, or just have a question or a suggestion? Email us — we read everything that comes in. CoinVac is run independently, so we can’t promise a same-day reply, but messages do get read.
What’s Useful to Include
- For a calculator issue: which tool, what you entered, and what you expected versus what you got.
- For a guide or museum correction: the page, and what looks wrong.
- For a tool idea: what you’re trying to figure out that none of the current calculators cover.
What We Can’t Do
We can’t give personalized financial, tax, or legal advice, recover lost crypto or coins, or act on behalf of any exchange, wallet, or authority — CoinVac isn’t affiliated with any of them. For decisions that affect real money, a licensed tax professional or financial advisor is the right call, not a website contact form.
