so i have  a little fear about this that if bitcointalk.org get closed what will we do.and how much chances for it.and why?

Bitcoins have become an awesome currency now. I think everyone should go for it. Investing in btc is not always good or bad, so thinking twice before investment is good. Also, going full time on btc isn't possible and recommended, so invest a little, spend some time. . And when you think it's the correct time,  go for it.

Since most of us have thought about the size of the blockchain, but what about the download speed.
Think of it this way, the size of the
blocks have to increase at some point to absorb more and more transactions , or the block creation interval has to become shorter .
If the block creation interval becomes shorter, then at some point we have to get to an interval of less than 1 second, and after that there will be more transactions / time, than the speed of the average user, thus he cant keep up with the exponentially increasing blockchain, and the network will fall apart. This is true with supernodes , because this doesnt depend on the bandwidth , but the connection speed, which is bounded by the speed of light.

Yes, it is completely legal to buy btc in US on exchange ad sell on another. Very few people know about it, but this can bring a lot of benefits and profit for you. It's completely legal and authorised by govt. So no problems here.

Seeing bitcoins popularity, many shops and stores in countries like USA and UK and Australia have started accepting bitcoins as a mode of transaction in their stores for various products. It's a good step as it will create awareness among people for using btc more and more.
Stores which have started accepting btc are
(1) Cloth sellers-- Local cloth retailers have started selling clothes for btc.
(2) Electronic gadgets like mobile devices, PCs are also sold for btc in some stores.

Yes, bitcoin is like real money to me because
(1) It's always present in my wallet like my real cash.

(2) It can be used for transactions like I do with real cash

(3) It is as convenient and simple as cash.

Yes, I think that soon the day will come when dollar will replace btc because of the following reasons.

(1) It's cashless. No hassle of cash. It's completely free from cash.
(2) It's safe-- No one can steal it from you. It stays with you wherever you go.
(3) Easy mode of transaction.
(4) Maintains your privacy.

Basically I would tell that Bitcoin supply and demand
Everything in the world of Bitcoin is about supply and demand – those two basic economic categories.

Following are methods to earn free btc
1- Visiting websites or doing small tasks
Another way of receiving small amounts of coins is visiting Bitcoin-related websites or doing small tasks on the web. There are numerous websites which provide this opportunity to earn some free Bitcoins
2- To get free Bitcoins fast with Faucets
 3- Getting Bitcoins through Trading
Trading is one of the most popular ways to start earning
Summary of my post:-

With Bitcoins being pricy, it is always luring to find a way to get some for free. While some rely on faucets or little tasks they can do for couple of hundreds of satoshis, others find more intriguing ways, such as gambling (where everything depends on the chance) and trading (where everything depends on your prediction skills).

Bitcoins currency have many advantages , but in recent times, some people are using it as an disadvantage by following
(1) Porn industry-- It's a secret industry and payments here are done in btc as fear of getting caught is less
(2) Drones and terrorism-- Many terrorists and terrorism groups use bitcoins for buying illegal weapons and drones.
(3) This is the most worst one, KIDNAPPING-- Many rich people are kidnapped and asked to pay in btc otherwise they'll be killed, this is not less than robbery .a few days ago, this has happened with a billionaire person in Hong Kong.

My last anBitcoins provide a simple and elegant payment way and method. I prefer btc than other digital currencies because of following reasons.

(1) No fear of stealing-- btc aren't coins, which a small kid can take out from your pocket

(2) More secure -- It's considered more secured as most wallets can be protected by PIN, and no fear of getting hacked.

(3) Many methods of earning-- Earning btc is easy as many websites pay you for posting and visiting their sites, whereas for real cash , u need to do some hard work..

The success story of bitcoins is hidden from no one. It has emerged as a new digital currency. And, guess what the world's one of the most tech giant country China has started buying bitcoins and they have also unofficially authorized the use of bitcoins in their country. They've taken this step as they think that bitcoins are the new globally accepted currency. It's a very good step and will give fruitful results in future

I'll choose bitcoin wallet here, because of following reasons.
(1) No hassle of credit or debit cards, it's completely wireless.
(2) No hassle of cash, so no fear of getting robbed or stolen, so you get complete safety.
(3) saves time, no need to go to ATM to fill your wallet, your money is always in your bitcoin wallet
(4) And, lastly, no fear of fraud

The biggest problem of bitcoin for me is that there's no official bank or community to look after the problems caused by it. Transaction issues or wallet problems are sometimes ignored by the providers and due to lack of any official forum (there are many unofficial forums), people sometimes get cheated. This is a negative view of bitcoins and needs to be tackled correctly
