If the sending party complains to Paypal, saying his account was hacked, you risk getting your account closed. You're not a friend or family, so don't use that option.

I've been playing agar.io for a while, then switched to chopcoin.io, and later switched to bubble.am. The last one is much faster, has more food, and has nothing^* to do with Bitcoin. Chopcoin is too quiet to be a good game, and that hasn't changed since it started.
Recently, I have discovered slither.io, and since then I haven't touched agar anymore. And that brings me to this quote:

I don't think Chopcoin.io has contributed to promote Bitcoin at all. This is not a complaint about Chopcoin, I think it's played by (a few) people who like Bitcoin already. Not by "new" people who have Chopcoin as their first Bitcoin experience.
For the same reason I don't think a Bitcoin-slither will contribute anything to promote Bitcoin.

If the original agar.io or slither.io games would start supporting a Bitcoin-game, it's a different story. That would reach a large group of people who have never used Bitcoin before. On top of that, it would instantly have a game with a large population of users.

^*bubble.am offers to exchange "points" you collect for Bitcoins, but they didn't pay out.

If you can't hold the gold in your hands, you're not the owner!

On my system this file shows where it is:
/home/loyce/.config/Bitcoin/Bitcoin-Qt.conf
I'm not sure what the default location is, as I've changed it by myself. Most likely your wallet.dat file is located in [homedir]/.bitcoin or something that looks like it.

Note that making a backup once is NOT enough! By default it contains 100 private keys, once you've used them all it creates new keys, which means you need to make a new backup!

As far as I know (but I can't find a confirmation online) blockchain.info's wallet stops broadcasting after a few days if it doesn't get confirmed. The funds will be back in your wallet, and you can try again with a higher fee.
Unless you're in a rush, I suggest you just wait.

Your transactions:
1: 9221 bytes, 0.2 mBTC fee.
2. 18074 bytes, 0.2 mBTC fee.
3. 8191 bytes, 1.0 mBTC fee.

The problem is your huge number of inputs. This creates a large transaction, and requires a higher fee. I had a quick look at it on blockchain.info, and you have a lot of inputs of a few mBTC or even half a mBTC (AKA "dust"). A minimum fee would be a 0.2 mBTC per 1000 bytes to get a fast confirmation.
My Bitcoin Core currently says: 0.10203 mBTC/kB gives an estimated confirmation within 25 blocks. Your third transaction reaches this fee.

You can double spend the coins with a higher fee. I've done it from Bitcoin Core, but it may be easier to wait a bit longer. What wallet do you use now?

Me being curious:
Why did you withdraw small amounts so many times, instead of a bigger amount at once? I'm not familiair with Lucky Bit, did it come from a faucet or something?

Very nice words for a pyramid scheme. Seems like you want people to give you money for something that is at best a ponzi scheme.
Don't fall for this!

Yesterday I announced that users gustavv, btcgreen , comvuse, revolutioner, sevenup, magicrush, aikonia, masova, kasawari and kompeni got blacklisted for claiming Free Tickets from ten different accounts. Amazingly, the cheater paid back his 3 prizes (41 mBTC total) today.
I will adjust the amount won from this giveaway in the topic title.

It's a lot like mining: if you double your processing power, you'll find twice as many blocks/addresses.
Vanitygen searches at random, so if you were to start it on 10 different computers, they all search different addresses.
You can look at it as trying to roll a 6 on a dice. If you throw 2 dice at once, chances you hit it go up! If you throw 20 dice, it becomes very likely to hit it very fast.

Shorena offers a service that also includes longer addresses. And for a reason:
You're requesting a prefix with 7 characters, that will take too much time (and power) for this free giveaway.
If you take 2 characters off it's okay, if you take 1 off I can make a case sensitive addy for you.

At 10 posts per day I doubt you're really curious, and not just posting a long post for signature exposure. Please don't!
Just search the forum for vanitygen if you're really interested, this topic is not the place to discuss thit.

I do have a (few months old) topic to give away Pretty Bitcoin Addresses. It was popular for a short while, and has since then been forgotten.
I'm not asking money, I just like creating nice addresses. It's a nice way to personalize Bitcoin a bit. If you would like to promote Pretty Addy Giveaway a bit, I can crunch some addresses again.

I got reminded about this topic! I've changed the title back to the original: Pretty Addy Giveaway.
It's time to make some more addresses. Let's personalize Bitcoin

Native Dutch here No references though, showing those would expose my real self, which I don't want.
Depending on the material to translate and your offer to do so, I might be interested.

Then your trusted friend loses the password, and you can say goodbye to your good friendship and your money. Not a good idea!

Don't expect doubling overnight. "In real life" investments produce a few percent per year on average, and the higher the return, the higher the risk.
On average the value of Bitcoin itself has been growing a lot faster, so "buy and hold" has been a good strategy.

I'm amazed the value of Ethereum went up after the hard fork. Greed wins from common sense? Is this the same way people "invest" in ponzi "doubling" websites? They know it's a scam, but hope to make a quick profit on the short run before the system (based on the greater fool theory) runs out of fools?
In my opinion Ethereum deserves to lose its value, and should always be remembered as an example of how not to handle a cryptocurrency. But it seems like it needs more time to die out.
