"Because of the progressing DDoS assaults, Cryptsy clients may encounter trouble in pulling back assets from their cryptocurrency accounts."

Seems legit , Cryptsy didn't allow their clients to withdraw since long time ago so it has nothing to do with their current DDOS attack (if there is any) . They will try to make a better scenario then Mt.gox and run away with clients funds if you ask me .
and if it's actually true (that a DDOS attack is happening) then I can't say I feel sorry about those people because I don't , and for what comes to the clients ... they couldn't take their funds before , so this changes nothing for them .

Bittrex have Alternative coins as far as I know , Kraken have also altcoins as I can see on their their homepage but not like Bittrex , Alternative coins may get you a good profit however make sure to invest in coins that you see potential on and not on every pre-mined created altcoin out there .
Now to answer your first question , I personally wouldn't use exchanges at all because they defeat the purpose of using Bitcoin on the first place (being anonymous) . Those exchanges ask for personal details such ID , Passport etc ... so I'd prefer to trade in forums like here on BItcointalk where there is Currency exchange section . I can trade with the rates that fits me and with any payment method I want . Good luck and feel free to ask any questions if you have some .

I agree , it could be very useful in some occasions like "Stake your address" for example , without the need of people quoting your replies in case they get edited later however when we enter the topic these information should be available like if we can edit our posts or not ...
Till now .. I don't know how I'm supposed to know if a reply has been edited or not .. so these kind of info should be visible to public .

People can make money using any over exchanges (including Localbitcoins) , the idea is simple , basically they buy low (when bitcoin price is low) then they sell it again when the price rise once again , however you need few bitcoins to start with so the trading is profitable otherwise you won't be making good profit at all .
also I suppose if you want to do buy low and sell high you should use some other exchanges because Localbitcoins is decentralized and may take time to trade with the users .

Honestly I think if they don't take their decision soon , maybe some developers are going to get bored after a while (I'm not sure if they get paid on the first place) and simply leave the project just like Gavin did and we will find our selves in a not beautiful situation ...
I don't think they will take any decisions but let's hope I'm wrong on this one . Maybe increasing the blocksize to somewhere so they don't increase it again anytime soon .

You are only allowed to post on the META while you are banned (to only appeal if you want to) , so posting here is against the rules and you may get your account banned for more time , if not permanent .

If you are going to play with NSA or CIA  or something then yes you will be traced and get police to your house . If it's just for normal use like visiting websites etc ... then you should be just safe .

Hell no , this is totally impossible and it will never happen .
If you said 1 BTC by 2046 would worth one million dollar then yeah why not (small chances , like very small ...) but one satoshi make no sense , so first let us break at least the 1000$ then we can talk about the future of bitcoin (for what comes to the price) .

Sure , I'd like to see a video about it please . Also , are you  willing to use an escrow on your transactions or not ?

I will try to answer what I can

1. "A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes." and you can run one of those Full nodes simply by running Bitcoin Core wallet in your PC and opening the ports .

2. I'm not sure what that means honestly , but basically the Decentralized part is that we don't really need any third party like banks etc ... and all transactions can be viewed by everyone everywhere on the Blockchain .

3. Basically nodes are needed , if there is no nodes or everyone is using Lightweight nodes Bitcoin could not exist .

4. Euro has it value on dollar as-well , just like anything else . It's just conversion ? (I hope I got your questoin right)
5. Bitcoin community is basically us , everyone try to contribute on the way he can  , some people open services that accepts Bitcoin , others try to speak about Bitcoin and how cool it is to their families or their friends etc ...

6. Supply halving is made so Bitcoin don't use it value with time , and no Miners don't really lose (maybe they do , but they will keep making profit) , I mean if they don't make profit , they will logically stop .
Also the miners owns the most of the bitcoins , so probably after the next halving which should happen next July ... price should rise (It's based on supply and demand , so less supply and same or higher demand should make the price rise)

7.What do you mean how it's editable ?

8. Mtgox claimed that they got hacked , and till now .. no body knows where are the millions of dollars stolen exactly , they are probably little bit everywhere (on different bitcoin addresses) and the suspect number one is their CEO .

9.You can't really know how much Bitcoin is lost ,it's pretty impossible . How it does affect the economy ? On a good way , as Satoshi said few years ago on this forum "Lost coins only make everyone else’s coins worth slightly more. Think of it as a donation to everyone"


10. What companies are we talking about here ?

11. I have zero knowledge on Mining so couldn't really answer this one , sorry .

12. I guess not (AFAIK) , but banks finally understood how Blockchain is good and some of them are even using the technology right now .

You literally copied everything (including the topic) from the other (Original) seller , Guys don't buy from him you are going probably to get either a virus on your PC or nothing at all or a cheap leaked version  .

I had the same issue and it only lasted few seconds and dissapaeared after refreshing the page couple of times .
@theymos , I assume that the database is busy because of some DDOS attack or just BadBear banning some people ? 

How those Steam wallet codes has been obtained exactly ? (If bought physically , please take a picture of them and share it) if not then tell me from where

Passwords can't and won't get changed by themselves , that's for sure .
Either you got hacked or you made the changes by your self and you forgot , I'm not sure if you are speaking about this account (but since you are logged) I'd assume it's another account ... So if you want to get your account back then you should provide a signed message using one of your addresses that you posted before and Theymos or BadBear should reset your account .

I just wanted to get your opinions on this one , what do you think Bitcoin would be if there was no Alternative coins such Litecoin & Dogecoin and the others ...
I mean it would be better with or without them Bitcoin would have no value at all ?

If you have good coding knowledge and skills then it's probably the best (beside designing , you can probably make more being a Photoshoper) . But as I said you should have some great skills because there is a big competition on this area and people don't need some basic knowledge to just run a blog made in WordPress or something . (so HTML , CSS , PHP etc .. are required) .

Now for Japanese learning , some people are interested on this I'm sure but you should expand and not only look to Bitcointalk , forums like Leakforums , HackForums etc ... have anime fans who would like to learn that language and hey also pay in BTC .

For shipping food  I can't say much I suppose , you should speak to Japanese people because I'm sure that you won't ship the food worldwide .. are you ?

Bitcoin it self is an investment however it's for the long term , so the more you wait , the higher chances to make huge profit .
Now if you want to invest in something else , you should check eToro and you can buy stocks etc .. (and as far as I know they do accept Bitcoin as payment method) In case you don't know anything about this , you can visit someones profile (someone who is actually making profit) and simply click "Copy" so you copy whatever he is doing and earn money as he does .
Website is available on  most countries , I know it's not available in my country (Algeria) , India & USA too I suppose .

You seem like you didn't send anything to that address because as I can see on BlockTrail it's pretty empty , I'm confused here , same for TX ID it seems like it doesn't exist .
Now and you refreshed my memory about "Rejected" on Bitcoin Core , are you sure you are fully synchronized with the Network and downloaded blockchain ? because last time I had that message on a transaction was when I didn't sync .

I assume you was trying to double spend ? that's why It got rejected probably ? Share with us the transaction ID & addresses so we can help you out .

Being optimistic is good but being realistic is better in my opinion , this is no sense .
There is no way price will reach 1000$ (at least not before 2016 , that's for sure) . We need at least to wait till halving block reward to see such price increase . 400$  shouldn't be that hard though .
