Kriptomist - a framework for crypto price prediction using fundamental analysis

Your Reddit submission is not even under the /new section anymore: http://www.reddit.com/r/Bitcoin/new/

I love Reddit, but didn't know you can get "buried" so easily??

5 seems like a nice number.

This is a project I've been working on in the past weeks: http://www.spaculator.com/

It's a silly app where people guess the daily bitcoin price of a chosen day and put a small amount of bitcoin to support their guess. The closer the guess, the bigger the reward. And there is no username/password required to login; instead, only a bitcoin address is required.

So yeah, you spend bitcoin to speculate on bitcoin and maybe get more bitcoin out of it. Feedback appreciated.

OK I put some jQuery dialog there instead of a popup. Hope it works now.

BTW payb.tc, since Spaculator uses bitcoin addresses as user account names, maybe your service (http://bitnot.es/) might come in handy.

I'm developing on *nix which allows select+copy on dialog boxes. Will fix, thanks for feedback.

You can now guess the future with this app: http://www.spaculator.com/

The benefit is a graph of speculated future values by all players.

This just launched: http://www.spaculator.com/

It's a silly game now, but maybe it grows into something like an options market in the future.

Check it out, feedback welcome.

Suppose you've just graduated in Computer Science, and for *some reason*, became interested in Economics. Where would you want to study, and what would it take to get there?

Thanks.

Always new feature requests huh? I thought in bitcoinland things would be different...

Agreed, I was in a hurry, just put the working version up and let it go. Would you consider making your qr-code genarator available via a public API (possibly with a fee)?

I'll update the page so it gives proper credits.

Half-baked, but might serve the purpose:

Thanks for your insight, very interesting. The way I see it now is, if the person holding the single-address account doesn't care that much about his money being stolen (like maybe he only keeps small amounts there), then this approach would be sane. I mean, I'm mostly concerned about this patch having a negative impact on some other unrelated bitcoin user, or the network as a whole. For example, could this behavior make another user less anonymous, or make some other client break (because there is a direct cycle - an input is the same as an output), etc...

Yeah, the idea is to have one wallet with multiple "accounts", as the client calls them. And only one address per account.

Hi,

suppose there was an online wallet service with a patched version of the official client:

The patch would:
- prevent the client to generate a new address every time it needs to put the money change somewhere
- instead, it would always put the change back to the source address

The benefit would be for the users to be able to check their total balance by simply checking their address on blockexplorer.

My question is, would this have any serious drawbacks, other than loss of anonimity?

I played with the idea of using OT + Bitcoin to create a currency for Reddit.com users:

Very interesting stuff indeed, I guess if systems like this are feasible, the limited supply of Bitcoins is no longer a problem.

Good luck!

So you are saying you would use such an app? I'm thinking of implementing it, want to help? http://spaculator.appspot.com/

+1 for keeping the existing name. Really, every person on the planet should be able to have at least one Bitcoin.

For the transition, people would call them something like small bitcoins (one millionth of the current BTC), and big bitcoins (current 1 BTC).
