We always pay enough fee to ensure your transaction gets speedy processing by the network. If your coins have a lot of dust and it costs 0.01 BTC in fees to spend, we will pay that and only charge you 0.0005.

Keep in mind that it costs us to do a instant transaction yet we don't charge anything.

They are 0.0001 multiples now.

Depends on the transaction priority. Hard to say and is very variable.

Multiple inputs increase the size of your tx so you may pay a higher fee

TX fee is based on size primarily because that is what matters. So for everything if it increases the size yes, otherwise no

Not all transactions will move off the chain. I would assume that at least for now people want to settle large transactions directly. Things like small transactions definitely will happen off the chain as long as the block size is not unlimited.

Eventually Bitcoin may move to a model where off chain networks pay large miners for insurance against double spending and then allow large transactions to be made on the Blockchain, without most people waiting for confirms if it is signed by a trustworthy entity.

Nice. How do you estimate the uptime? We might use this for Inputs (and stop paying for forex rates).

Also, if you add an inputs.io/1v.io address there we'll tip you

Other exchanges were not better. I won't say more.

I was pretty much shocked at the amount of attention paid to security for bitcoin web services. Originally I thought MPEx were absolutely crazy, but now that's actually a pretty good method if you expect your users to jump through the hoops.

Sure, I'm happy to do that. It would be an unwise idea to take a loan like this from a financial point of view, but if you want to I won't stop you.

The easiest way to protect yourself would be using web applications that are coded securely. Now I'm not sure if btct.co uses an anti csrf token (I don't think it does?), but their PIN / 2 FA system makes this attack less useful (an attacker can just use JS to submit ~100 most common PINs)

The same vulnerability still works, just in a slightly different format, FYI.

If you're still looking for help, I charge $70 / hour. I'm pretty good with bitcoind (having built multiple instawallets, bitcoin payment processing services, etc), JS (coinchat, blockchain.info my wallet) and security (having found security vulnerabilities on bitcointalk.org, bitfunder, btct.co, and a bunch of smaller sites). I'm pretty sure you'll feel it's worth every penny.

Coinchat is officially myspace.

(Yes, fontas paid 2.5 BTC for rainbow colors. Thanks fontas!)

Thanks Skype!

No, I was referring to a method which had the same effect for you, but I assume no risk

Change the password and email yourself, get a GPG signed contract. There.

How about this:

Pay me 0.25 BTC and I'll gamble it for you. If I win, I'll give you your 0.1 (0.25 - 0.15 interest) BTC back plus profits of my gambling. If I lose, you lose.

Should be just as fun

I could, but all modern browsers use a font that distinct 1 from i, lowercase all URLs, and we already have the anti phishing bar

Thanks for the feedback!

What we're about to do (after all sessions have expired and people would have upgraded their account security) is to make it so that an attacker cannot steal funds even if the web server was compromised. This is pretty much what you described, except for making transactions instead of just logging in.

Focusing on preventing transactions is more important than logins.

Umm, that's shorting.

You need to log out.

0.02 BTC (namecheap push)

Step 1. Buy bitcoins, complete AML / KYC checks
Step 2. Mix them through Inputs.io
Step 3.
