How is this better than some other service that guarantees user's safety (For example,
this)? AFAIK creating a vanity address on your own will give the full control of the private keys to you. Which means it's not safe at all
Making vanity addresses using split key method gets you full control. Many people provide vanity addresses service like me. The safety is minimal if I have a wish to take your funds.
I'm looking for people who get this service for fun and not for serious bitcoin holders. I always don't encourage it.
do you mean for collection ? if you have vanity address on hall of fame i will buy it now
Yes, I prefer and wish people to have it as collectibles. If you get a vanity address from me, then I and you have private keys. Causes are there at some point I may take your money if you have any there(Scam or cheat or some otherthing). However, these chances are minimal. If you use split key method, then I can't take your money.
