INTOTHEBLOCKCHAIN.info is a bitcoin SaaS written in NodeJS that I am now putting up for auction.
No ads needed, users pay 0.0005 BTC to embed a message into the immutable Bitcoin Blockchain forever, and funds will go to site owner's wallet.
The site owner can accumulate roughly 1 BTC for every 2,000 messages embedded.
Site owner has to do nothing aside from renewing the domain name once a year and run a VPS for the site to run on (~$5/month).
Auction is taking place at flippa
