Looking at Bitcoin's massive value increase via YEARLY LOWS
Are you tired of those who predict Bitcoin's collapse and death every time its dollar value decreases by 1%?
By looking only at the yearly lowest dollar value you'll find out that Bitcoin is always  more expensive in a given year than in the previous year. On average, its dollar value increases (at least) 325% p.a. on average (2010 - 2018).

Is it a cryptocurrency or NOT?
Today, there are more than 2500 so-called cryptocurrencies out there. But the question is: Are all of them actual cryptocurrencies?
What if some are created by a centralised organisation that decides who can and can’t use it? Are they all neutral, borderless, public, censorship-resistant and open?
Let’s take a closer look at five key characteristics of a real cryptocurrency and compare it to digital money created by a centralised custodian.

All Bitcoin Private Keys LEAKED on the Internet?!
There is a finite number of Bitcoin addresses. When you create a new wallet, both public and private keys are randomly generated. That means your wallet might actually belong to someone else if you both generate the same keys.
A private key is basically just a number between 1 and 2^256, so there is a chance that more people will share one private key. What if I tell you that the private key of your wallet can be found online?
For example, the website KEYS.LOL helps you browse all existing private keys on the Bitcoin network.
So what's the catch?
Well, even though it's true that all private keys are visible and accessible, there are so many of them that it would take an impossible amont of disk space to store all of them. That's why this site (and some others) shows only a few addresses at the same time.
