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.
