Frequently asked questions

FAQ

Is Invity licensed and regulated?
Yes. Invity Finance s.r.o. operates under EU financial licensing with full MiCA compliance. Your activity is protected by the same rules as any regulated financial service in the European Union.
How is Invity different from an exchange?
Invity is not a trading venue. It is an accumulation-first app designed to make buying, holding, and moving Bitcoin effortless. There are no altcoins, no leveraged products, no trading pairs — just clean flows for Bitcoin.
Who holds my Bitcoin?
You choose. Your balance is held by a regulated institutional custodian, segregated from Invity's operating funds. You can withdraw to your own hardware wallet or any Bitcoin address at any time. You can also set our Auto Send function to any address when your stack in the Invity App reaches a certain amount.
What fees does Invity charge?
Invity uses transparent per-transaction fees displayed before you confirm any purchase. There are no monthly subscriptions.
What is Turbo Buy?
Turbo Buy adds 60% extra buying power to every recurring buy. You pay a fee only on the extra. Your stack secures it — there's no debt and you can never go negative. The only Bitcoin at risk is what's inside the plan.
Which countries are supported?
Invity is available to residents of the European Economic Area as per the MiCA licence. The current list is displayed during sign-up.
Can businesses use Invity?
Yes. We offer business accounts for companies that want to hold Bitcoin on their balance sheet or offer Bitcoin-related services to their customers. See the Business Accounts page for details.
How do I contact support?
You can reach us via in-app chat or email. Support is provided by real people based in Prague, typically during European business hours.
How can I close my account?
Open the Invity App and go to Settings → My account → Delete account. If anything is bothering you, talk to us first via Settings → Contact support — we'd rather fix it than see you go.
