The actual headline is "Anonymous hacks ISIS site, replaces it with Viagra ad". The article is not about Bitcoin and only mentions it in passing:

The article is unrelated to Bitcoin, and there are even people quoted in the article saying how it is unrelated to Bitcoin.

And what does that headline even mean? CoinTelegraph is the worst. Their artist, Dennis Spaans, is the only there person with any skill. He should join a real news outlet, and get paid a decent amount, too.

Here is another analogy:

There are approximately 1x10⁴⁴ molecules of air in the atmosphere.
There are 1.46x10⁴⁸ bitcoin addresses.

Suppose I pick a single molecule of air and I generate a single bitcoin address. If you also pick a molecule of air and generate a bitcoin address, you are 15000 times more likely to pick the same molecule than to generate the same bitcoin address.

Here is another analogy:

There are around 5x10⁴⁶ water molecules on the earth (1.4x10²¹ liters according to the USGS)
There are 1.46x10⁴⁸ bitcoin addresses.

Suppose I pick a single water molecule somewhere on the earth and I generate a single bitcoin address. If you also pick a water molecule and generate a bitcoin address, you are 30 times more likely to pick the same water molecule than to generate the same bitcoin address.

That's not such a stupid idea.

If you have an amazon gift card, you can convert it to BTC at purse.io. You buy something for someone and get repaid in BTC.

Currently, in order to receive 1.1 BTC in revenue per day, you must have at least 160 TH/s.

How long did you have the position open?

For a trade of 10 BTC, the open fee is .045 BTC, the close fee is 0.045 BTC and the daily fee is 0.03 BTC.

If you bought 10 btc at $325 and sold it at $360, then your profit before fees is $350 or 0.972 BTC. If you held the position for 26 days, then total daily fee would be 0.78 BTC. Subtract the 0.09 BTC opening and closing fees and your profit is 0.102 BTC

I sure hope this isn't a huge ponzi scheme.

I did some analysis. Because the $1.20 per TH/s per day maintenance fee seems to be more than enough to pay for operating costs, I am less suspicious of Genesis Mining.

However, my analysis also shows that if the difficulty increases 2% per period, then the 1000 GH/s contract lasts for 535 days and never recoups the initial cost.

Here's a novel idea! How about just joining and reading, and posting once in a while when you have something useful to add?

Most people here just post whatever shit spews from their tiny brains so that they can get paid a few pennies. That's why you rarely see any important people posting here these days. Their posts are drowned in the rivers of sewage. The quality of this site is way down.

I received my Kialaras today. They are very nice!

Not worth reading. Its a typical low-value JP Buntix article. It talks about renewable energy and mentions Bitcoin, but doesn't really say anything.

Saying that "a bitcoin transaction is irreversible" is a simplification. A transaction is not reversible in ordinary circumstances, but...

Without getting into too much technical detail, a transaction can possibly be canceled before the first confirmation by simultaneously making another transaction that spends the same bitcoins (so-called "double-spending"). If the competing double-spend transaction is the one that is added to a block, then the original is canceled (and thus reversed).

It is possible for a block in the block chain to be replaced by another block. There is about a 1.5% chance of that happening to a newly added block. So, even if the original transaction is added to a block in the block chain, there is a small chance that the block is replaced by a diiferent block that may contain the competing double-spend transaction, which would cancel the original transaction.

The permanence of a block depends on the number of blocks that follow it, so waiting for a certain number of blocks (typically 1, 3, or 6) reduces the chances of becoming the victim of a double-spend.

It's odd that they banned him instead of fixing the problem.  Now that people are aware of the exploit, they are going to play with it and Changetip is just going to look stupid.

Clicking on facets is a horrible waste of time. 0.004 BTC per day is only $1.32 at the current price. That's pretty bad even in countries where the per capita income is only $5 per day.

In order to prevent all possibility of tracking your bitcoin addresses, you must mix bitcoins both entering and leaving the wallet.

If you don't mix bitcoins leaving the wallet, then your addresses and all your spending can potentially be tracked by anyone that you send bitcoins to.

If you don't mix bitcoins entering your wallet, then your addresses and all your income can potentially be tracked by anyone that sends you bitcoins.

Something else to consider: the mixer can track everything.

Localbitcoin traders: Please don't risk the safety of your customers by selling their trust to BitcoinPROs.

The purpose Person B inspecting the goods is so they can cancel the trade if they aren't satisfied. So, no matter how the deal is arranged, they will want to be able to cancel it after they have seen the goods (and potentially copied them).

The only way to solve this is to prove to them that they are getting what they are paying for without showing it to them or prove to an escrow/arbitrator that they got what they paid for.

Higher interest rates is not good for bitcoin. It will cause money to be pulled out of bitcoins and moved into bonds.
