Hey, I noticed that you also sent me a PM:



Now, it's ok that you sent me a PM, np.

But you should know that PayPal shall never be used with bitcoin transactions. Nothing personal, but most "paypal for bitcoin transactions" ends up with charge-backs after months of the transaction. A bitcoin seller just cannot trust people using PayPal and therefor I recommend you to search for a different payment method.

Why? With this vulnerability attackers can get ~64KB of random data from the memory, and an attacker can keep doing this to get more memory data. In the memory data there can be sessions IDs of users so the attacker can take over their session and for example do a BTC withdrawal. This is widely documented already, for example: https://www.mattslifebytes.com/?p=533 , https://www.michael-p-davis.com/using-heartbleed-for-hijacking-user-sessions/ , etc. and the scripts for it are pretty easy to find too.

Do you really enjoy people losing their money or something? I am just trying to warn people for a serious security vulnerability :\

What are you talking about? It gives part of the memory as proof :s


Just to be clear: anyone using BTC-arbs last few days should be very careful. An attacker can steal user's cookies/password as long as btc-arbs.com has this OpenSSL vulnerability. I recommend to not use this site until this vulnerability is fixed.

And well, obviously I recommend to not use them at all since months already but yeh. Will be perfect end for ponzi too "ah shit, got hacked".

'k so I will keep it, thanks

That page says "btc-arbs.com IS VULNERABLE. " ?

Windows Phone's market share is very small.

I'm not sure but I think all you can do here is say "email/sms me when money got moven out of bitcoin address x". So how is this a wallet stealer? Sounds like cool service.

Everyone who uses bitcoin should follow some basic security measures like disabling JavaScript by default (NoScript for FF) and obviously disable Flash/Java/etc. So I do recommend to only open links on bitcointalk if you have basic security measures like that. I always recommend reading this for a start: https://en.bitcoin.it/wiki/Wallet_Security_Dos_and_Don%27ts_(Windows)

Ok I will most likely join.

Just 1 question: what happens if I have for example 40 posts in 1 month? Would I be paid 0? Or 0.08/50*40 = 0.064? Or I will just keep it 1 week longer? Or ? :p

Don't really expect that, but I don't like these "pay per post signature ads" so I like this alternative, just wondering what happens if I don't reach the min. post.


In case you will be flexible with that (by either extending time or lower reward):

Yes.

Not really a false negative because the vulnerability is not any more there. But yeh if your server was once vulnerable, you should consider the private key of the certificate as stolen and potentially even users' cookies/passwords. That's why I assume bitcointalk.org never had this vulnerability because I am sure theymos would have made a topic about it then (with a warning to change our passwords to be sure.)

Sounds cool

I am a bit worried that I might put a lot of time on it and then end up not winning it.. so I will still consider.

Aww Firefox on Windows only then

Thanks Unfortunately it looks completely fucked in IE, Chrome, mobile browsers and probably Safari

For those who are not using Firefox:




Obviously not serious attempt since it only works in Firefox... but I enjoyed making it

CoinBase is actually the only one who does "set" prices right? Since it's not an exchange.

I can't blame you for included it on your site, but yeh it's not really an exchange

theymos is admin and in theory you can PM him.

I am however sure he gets - a lot - of PMs and I am pretty sure he will not reply to all.

Generally if you have a question about bitcointalk or whatever you can also just ask it here.

* also this topic should be in forum "Meta", I think you can move it with the link "Move Topic" on the bottom left. But I also reported it so a moderator could move it.

No collateral, no loan.

There seemed to be some issue with your macbook sale too: https://bitcointalk.org/index.php?topic=459411 you stated that you will use escrow, then in PM you ask them to send BTC first even if they suggest very trusted escrows. Seems sketchy.

Well personally I would pay coffee with cash. But I understand what you are saying.

In the Netherlands we don't use much creditcards but Maestro debitcards instead, and I had a quick look and paying with that costs € 0,07 - € 0,31 per transaction* for the merchant. I guess the difference is that the merchant pays it and the customer doesn't notice any costs directly. (obviously it is calculated in the merchant's cost so the product price would be higher and the customer does notice it indirectly.)

I also know that online payments in the Netherlands mostly go through iDeal (connected with all banks) and the costs for that are around € 0,45 per transaction. Creditcards 2,25% + €0,25 per transaction. PayPal 3,4% + €0,35 per transaction.



So yeh, in the end "even" with small transactions I guess bitcoin is much cheaper. For online transactions always much much cheaper. It's probably just the idea that you pay it directly as the customer and not the merchant (and you indirectly.)

Also if the merchant charges €2,00 for coffee for people who pay with debitcard and €2,00 in bitcoins + your bitcoin transaction costs, it is still more expensive with bitcoin since you are indirectly paying for the debitcard costs of the merchant already too.

I do think bitcoin is still in the beginning of acceptance so perhaps this will change. Like merchants can specifically say that they charge you 0.0001 less for transactions fees (obviously only relevant for the smaller payments) or even some discount if accepting bitcoin is cheaper for them.


EDIT: there are also examples of websites who do implicitly charge transaction fee. Best example in NL would be the biggest Dutch website to order food online: thuisbezorgd.nl, they say:
iDEAL: € 1,00
Creditcard: 6% of total
PayPal: 6% of total
Bitcoin: no transaction costs.
That's great I guess. In that perspective that €0,032 euro transaction fee looks really cheap, even on a small food order.


* With 1000+ transactions it's € 0,07 - minimum of 100 transactions which is € 0,31 per transaction. Excluding any "normal" monthly/yearly bank account fees.

Yeh, you can make internally fee-free transactions on inputs.io.

Oh wait.

Seriously tho, it would be decentralized and you (and the receiver?) would need to trust that service, which you shouldn't.

TBH 4,6 cents on a small transaction can be relatively much. Of course on a million dollar transaction it's nothing. Even on a couple hundred dollar I guess it's no big deal. But if you want to buy coffee every day with bitcoin IMO 4,6 cents is too much. Solution? IDK (I assume the solution now is to buy a $50 giftgard for your coffee or something so you only have to pay transaction fee once.)

Ah yeh, works best in Firefox. Also was not really serious attempt but it looked funny xD

Gotta stand out

Surprisingly does work for senior.
