How Bitcoin Cash exists? Bitcoin Cash is originated from Bitcoin. It's all come from the issue of the scalability of bitcoin. On August 1st 2017, Bitcoin is being split to Bitcoin and Bitcoin Cash. In other words, Bitcoin Cash is essentially a clone of the existing Bitcoin blockchain with stronger feature which is the additional block size capacity. Those who owned Bitcoin before the split now own an equal amount of Bitcoin Cash. It also means that Bitcoin Cash and Bitcoin each now have 16.5 million units in circulation. Why Bitcoin Cash and Bitcoin Splits? This is all goes to the history of how Bitcoin was first introduced back in the 2009, block sizes were unlimited.

In a cryptocurrency startup firm, if they would want to raise money through an ICO, it usually creates a plan on a whitepaper which states what the project is about, what need the project will fulfill upon completion, how much money is needed to undertake the venture, how much of the virtual tokens the pioneers of the project will keep for themselves, what type of money is accepted, and how long the ICO campaign will run for.

The easiest way to understand private keys is to think about an old-fashioned mailbox system: Let's say Maria wants to send mail to Peter. First she needs to know what Peter's mailbox address is. Let's say Peter's mailbox is number 2001. Similarly, if she wants to send Bitcoin to Peter, she needs to know his Bitcoin address, which is a number that uniquely identifies him. This is also sometimes called his wallet address or public key , which functions similar to your bank account number. It's a long and complicated number because there are so many Bitcoin post boxes in the world. So now Maria deposits the Bitcoin in Peter's mailbox. She can have a peek inside and see the Bitcoin there, in fact anyone who walks by can see that mailbox 2001 is filled with one Bitcoin. This is part of the exciting part of Bitcoin - that everyone can see all the transactions but without an...
