Pay for real visitors, in Bitcoin.
Put your banner on verified sites, choose how you pay, and let a transparent auction set the price. No contracts, no insertion orders.
Why advertise on j2x.net
Bitcoin balance
Fund your account in BTC. The balance is kept in satoshis and every change is written to a tamper-evident ledger.
Three pricing models
Pay per valid click (CPC), per 1 000 viewable views (vCPM) or per conversion (CPA, reported with a server-to-server postback).
Fair auction
Every view is a real-time auction with a second-price (GSP) win: the best bid wins and pays only what it takes to beat the runner-up, never more than its own bid.
Valid traffic only
Suspicious clicks are rejected as they happen. A nightly cleanup cancels invalid traffic that slipped through and refunds it to your balance.
Live statistics
Views, clicks, CTR and spend for every campaign and every banner, with the period you choose.
Banner builder
Upload a GIF, JPEG or PNG in any of eight standard sizes, or design a banner in the browser.
