I am not sure what the difficulty is for the addresses with numbers mixed in, but it generally takes me under a minute to create those.

How long did it take for you to generate the address with only lowercase letters and no numbers, and what kind of specs did the AWS instance have?

You're referring to 1woukheyeacxfpxtpkxjqxureevdkbywj? I spent about a day and a half on that address with several dozen instances of various sizes.

Few ideas for some more typical bitcoin address :
Is it possible to have a bitcoin address with no alphabets ? If not what is the possible minimum count for alphabets like this addy 1111111111111111111114oLvT2

- address with no alphabets 1nnnnnnnnnnnnnnnnnnnnnn
- address with minimum alphabets at the end : 1nnnnnnnnnnnnnnnnnnnnAa
- address with minimum alphabets at the beginning : 1aAnnnnnnnnnnnnnnnnnnnn
('n' can be any number).

In principal, it's possible to generate a bitcoin address that is all numeric, but the compute cost would be trillions of dollars.

An address with 17 leading digits has been done (I have 15375934619214243fGk3c5abbwcyVsBVM, for example), and I suspect making one that's at least 23 digits total (with some letters interspersed) is possible.

and would like to ask for a uppercase and a lowercase both.

If you use both, do not import them into different wallets.

how secure is this op I now it in too part but if hackers get hold of one side they might find away round this is yo program that u use 100% hack proof as doing this might put you wallet at risk it a good idea o make it easy to remember but letting a third party in on the security of you wallet is a bit risky I think

I don't recommend using more than one address that's been generated with split-key using the same public key, but in general this is quite safe. People have been using it to securely generate vanity addresses for years.

There's a link describing this in my post - repeating it here for convenience: https://en.bitcoin.it/wiki/Split-key_vanity_address#Address_generation_outsourcing

A few other references:

I guess I will satisfy myself with an uppercase address then. No need if you are trying to make it ready just that I had requested. Anyway curious about the software you developed. Also mind telling me what is the difficulty of such addresses ( I mean one you are doing it right now) and power you are having.

The difficulty for all lowercase, no numbers except for the leading 1 is about 1.16x10¹³, and for all uppercase, no numbers except for the leading 1 is about 2.81x10¹². I do the computation on AWS. The software is based on libsecp256k1. The free addresses will all have numbers mixed in.

I am not sure what the difficulty is for the addresses with numbers mixed in, but it generally takes me under a minute to create those.

Can you do me an address without no. and has all lowercase letters included just like you have for donation?

That kind of address takes a lot of processing power to generate, so you'd have to pay for that. I'm not quite ready to do that yet, but when I am it will be several hundred dollars worth of BTC. If you're interested, I can PM you when I'm ready.

hm... both types are cool but I would prefer uppercase

is it possible to buy all lowercase, too? If yes how much?

Here you go. Please be aware if you use both of these addresses, the private key for one can be computed from the other. I don't recommend importing them into different wallets.

So you are taking from $200 up to $500 just for an address including no numbers except the 1 at the beginning? then we must do a large transaction for it to worth the money lol. I want an address with prefix ImHash and will get it from loyce for free.

Some people like such things. If you don't, that's fine by me.

I went through all the steps and got my address imported. Still looks like a typical address until you look closely, wish there were less numbers Roll Eyes

Thank you and good luck with your business.
