With blockchain.info, you're still trusting your money to a third party, and they could run off with your coins get your coins hacked etc.
But blockchain is run by a company with an extended validation certificate, a large customer base, a valuable brand, etc. Whereas nxtwallet.com is a website on a privacy-backed domain with a self signed cert that could disappear tomorrow taking a few gullible people's keys with it.
I don't think OP had that intention, and it's good that he has now included a big disclaimer in the first post.
Question: how easy is it for people who run public nodes on 7875 and who dont want to give people the opportunity to enter their passphrase to remove the "unlock account" button?
