User Velkro and their private key stealing vanity generation site BitcoinVanityGen (.) com <-- SCAM has caused significant financial harm to many people when he stole their coins. No one wants to see a repeat of this and thus anyone offering such a service can be considered high risk, making TryNinja's trust feedback valid. "You think that trading with this person is high-risk."
The user also told people to trust him when announcing the service. People are making a big deal because you could be preying on those new to Bitcoin who wouldn't know how to use split key or the risks of having you generate a vanity address for them.
Well categorically I appreciate the intent, but you don't need to trust me anymore. Split key has been added to the website - mathematically removing the need for trust.
That is a shame what he did, but now this service will be known as the most affordable and legit service that even allows split key
Please spread the word of this legit, and amazing service
