What the hell !! ..is happening to cryptocurrency in july 2017 ?

The e-currency is a surprise of the times and this is due to its rapid development, as it did not pass decimal on the emergence until it began to compete monetary currency and increased interest of the international community and has been invited even confessions by the official governments of major countries such as the United States and China and The most important feature is the lack of stability in value as it ascends quickly and descends rapidly but overall is on the rise and at a high rate not seen by any other currency.

But most of what is not known about it is the source of this currency, there are many people working in them .and is the main source of their livelihood, but do not know what is the source ?and is there any real exchange for them?, such as gold or silver, and what are the criteria that control the rise and fall value ??....

Some numbers and statistics :

the total market cap for all cryptocurrencies just surpassed $100 billion. The vast majority of these gains have come in just the last few months — on April 1st the total market cap was just over $25 billion , representing a 300 percent increase in value in just over 60 days.
While some of these gains are from bitcoin is up 160 percent in the same two-month time frame, other digital currencies like Ethereum are also responsible for the increase, which on its own has increased 439 percent over the last two months.

For years this had always hovered around 80 percent, but in the last few months has fallen to below 50 percent — with currencies like Ethereum and Ripple taking its place.

It’s hard to be an experienced investor, or even an at-home part-time trader, and not think of a massive bubble when you see that some asset has increased more than 400 percent in just a few months. It’s just how history works — when an asset rises that fast it’s a near certainty that it will come back down. Markets are irrational, after all.
So don’t be surprised if there’s at least some type of correction. There already was, a few weeks ago — bitcoin pulled back from a high of $2,700 to around $2,000, but, as of today, has slowly climbed back up to a new all-time high of ~$2,850.

That being said, we may look back in 12 months and realize that this two-month period of insane growth was less of a bubble and more of a rebirth of cryptocurrencies as a whole.

The public has never been able to put their money directly into a technology that has so much potential but is still developing.But is still developing,

For example : "a technology enthusiast in the 1990s may have foreseen the rise of the internet, but had no way to directly take a stake in the technology".
....The idea of ​​applying cryptography to the storage and transmission of data is still very new. And the fact that anyone can directly buy the currency that powers these cryptographically secured blockchains is much like the public actually getting a chance to invest in the Internet during its infancy...

Cryptocurrency source :

There is one rational explanation that, if true, would totally justify this rapid increase in price across some of the major cryptocurrencies. And that is, maybe these currencies are actually worth these high prices, and maybe even worth many times more than that at which they are currently trading.
But the problem is we have no way to figure out their value. Cryptocurrencies are not public companies with incomes and expenses and EPS. For example, we can look at Apple's financials and determine its book value - what the company's assets would have worth if hypothetically liquid today. Of course, stocks trade at a premium to this, because people are enthusiastic that Apple will continue to perform well and this book value will continue to rise.
But we can not do this with cryptocurrencies. We could guess - and compare it to things like the total money or gold supply in the US. For example, if you're someone who thinks of cryptocurrencies as a store of value, the total estimated value of all gold in the world is more than $ 8 trillion dollars ... meaning if bitcoin would ever replace or supplant gold, its current value is pennies On the dollar....
