That logic tho...

var bitcoin = mathematical; var Woz = mathematician; var btcNum = 21,000,000; var btcSystem; var otherSystems;

if (bitcoin == mathematical && Woz == mathematician && btcNum == 21,000,000) { btcSystem > otherSystems };

Under the new policy, Google said it would ban advertisements for cryptocurrencies and related content such as

Initial coin offerings,
Crypto exchanges,
Cryptocurrency wallets,
Advertisements providing trading advice.
ICO Ads.

This will first result in a massive media coverage and as a result cryptocurrencies will be known by more people. Therefore, those who own cryptocurrencies would be more reluntant to sell or give up theirs—ultimately decreasing the supply. This is because they know cryptocurrencies will be hard to obtain in the future.

Because it's practically impossible to do solid analysis and make a sound, rational investment decision. Instead, many people are simply gambling on "great future". Whatever it is.

This depends on two things:

Whether you can afford to lose the investment.
How well you know cryptocurrencies.
Currently, this is an asset class that is still untested, so the clear-headed advice is to invest money you won’t be missing any time soon.

Then, you need to know the ins and outs of owning cryptocurrency. Keeping Bitcoins on an exchange means you may lose them immediately.

This is a tricky question because the term "bitcoin" is thrown about quite loosely and has been used to refer to a number of different things.
If you're referring to "Bitcoin" the cryptocurrency, I'm sure it'll still have users. I suspect the real question is how widely it'll be adopted because of its volatility.
If you're referring to blockchain technology, the technology is almost certainly here to stay.

NO..

Bitcoin is currency not a scam. It is digital currency indepedent of any govt. organisation

Even following MNC’s are also accepting bitcoin:-

Expedia. com – Online travel booking agency
Subway – Eat fresh
Dish Network – An American direct-broadcast satellite service provider
Amazon – that sells almost everything
Microsoft
Paypal - online payment gateway
etc..

Can't tell you overall, however heard that in Russia they did the poll and results were 50% of the people. Take in mind, that's in the country where cryptocurrency is banned. Therefore I believe that 5% of those who heard about it know how to buy it and use it, and 1% of those know what it actually is. Although it's my biased opinion.

The future of cryptocurrency is very bright. Currently, you can very well judge that almost every government across the world is trying to regulate cryptocurrency dealings. They are really terrified by this decentralisation thing. They know that it will do harm to them if they lose control of the financial system. Moreover, cryptocurrency is proving to be effective, efficient and free from old financial barriers.
As per latest cryptocurrency news published on sites such as CryptoFlash, Bitcoin will act as a flag bearer and it will be followed by other cryptocurrencies. Currently, Ethereum and Ripple are getting ranked higher but in future there are complete chances that some other cryptocurrency will take their place. May be Stellar, Dash, Litecoin or Neo…

In this posting, I break down the question like this:
Governments can ban Bitcoin, but the ban cannot be very effective. So, typically, they use other means to discourage Bitcoin ownership and trading.
But more to the point, what is the reason for these efforts to discourage use? Are the reasons and goals practical and legitimate?
Does Bitcoin present a threat to sovereignty, control of the domestic money supply, borrowing, inflation, foreign exchange or fiduciary institutions? Yes and No…
Gradually, lawmakers in some countries are beginning to perceive Bitcoin as more of an opportunity than a threat. There may be no need to dissuade citizens from adopting Bitcoin, even if the populace saves or spends it as actual stored-value cash and not just as a payment instrument.
