I dont think its really necessary. It was mentioned in the r/gonewild thread but its easy enough to use coinad or a similar service to get the address into the chain. Maybe if you can give a good example of why someone would need to use a firstbit IMMEDIATELY! how much would you charge for premium bits?
Girl is naked and has a marker in her hand?
edit for elaboration:
compare:
1. go to instantfirstbits.com
2. write your firstbits wherever appropriate
to
1. go to instawallet.org
2. go to coinad.com
3. copy address from instawallet to coinad
4. wait an hour (maybe more, just keep checking)
5. go to firstbits.com copy and paste address again
6. write your firstbits
It isn't even close. The difference for me and probably you is remembering to do whatever we needed it for an hour later. For most people it's the difference between doing it and not.
so its good for girls who want to get naked but who else? I do understand you point. Having another webwallet cant hurt and it will offer a few different features. There are lots of girls willing to take there clothes off too, if r/gonebits and other similar things become more popular Im sure a lot of girls would be using it. A long with other customers.
3. no idea. not a lot considering you can make your own vanity address. on the other hand I feel a large majority of the people using webwallets dont have the knowledge. one problem is that you can have duplicate vanity address rendering it useless as a firstbit.
How much do you expect a site like this to make? Id say most of your income would come from advertisements? Depending on how much and how popular the site was more to come from vanity address.
Well, no you can't have a duplicate vanity address.
If I put 1sgt1rh894vhnuiah428f943hj2z into the blockchain, and no one had an address starting with 1sgt in the blockchain already, then my firstbits would be 1sgt. If someone else put a new address, 1sgt3u19rjfio3wan5sj4j3fj4 into the blockchain, their firstbits would be 1sgt3. No duplication.
I have no idea how much the site would make, or even if it would be worth it to make. That's why I am trying to gauge input from potential customers.
Would 0.05 BTC/month per premium address be reasonable, or 0.5 BTC/month, or 5 BTC/month? Hard to say... I really have no idea.
Well I know im just saying it will get longer. I guess all you need is a warning or a disclaimer that there can be duplicate vanity address OR you can keep track of all the vanity address you have given out and not let any two people using your service use the same vanity gen. 1springs934859583ndnsjdsd and 1springs20580589384. The second guy would have to use 1springs2 which is getting longer still easy to remember especially being a word but may be annoying. People arent smart Im sure you will have cases where people will get a vanity address and not know they need to include characters after the vanity. where 1springs2 tells people to use 1springs because he doesnt know any better and ignores the warnings.
1BTC/month to 0.05BTC/month sounds like a good range.
BTW I do think the site is a good idea and will offer features that competitors are currently lack.
