Quick answers

What does it cost?

The fee page states 0.50% per prediction order, on top of applicable venue fees; cashback is conditional and must be claimed.[1][2][3][4][5]

Does it trade for me?

The reviewed sources describe user-directed orders, without documenting automatic prediction copying.[1][2][3][4][5]

Where do my funds sit?

The provider says users control funds, while its terms describe third-party key management for relevant wallet services.[1][2][3][4][5]

What do I need to start?

A connected or embedded wallet and funds in the separate Predictions balance.[1][2][3][4][5]

Where is it available?

A browser terminal; venue, account and jurisdiction restrictions apply rather than a universal access guarantee.[1][2][3][4][5]

Overview

Getting started

What you need first

The terminal accepts a connected wallet or an embedded-wallet route and requires a separately funded Predictions balance. The reviewed pages do not establish every current deposit route for each account.[1][2][3][4][5]

Safety and terms

Custody and keys

The homepage describes self-custody and connected or embedded wallets. The terms separately say a third-party service manages signing and recovery keys and that Nvio does not control that management process. These are provider descriptions, not an audit of every funding path.[5]
