While we will not get into the specifics of bitcoin (BTC) and bitcoin cash (BCH) here, but bitcoin is the world's first decentralized cryptocurrency with a public accounting system known as blockchain distributed ledger technology. While you may care less about the technical aspects of things, it is important to note when investing into bitcoin you are investing into the blockchain to keep track of everything for everyone so there is no double spend or network attack.

 So when you want to invest in Bitcoin you are basically buying the currency. However, there are also some other forms of investing in Bitcoin.

The banking system is open to manipulation of figures, exchange rates, and tampering by high profile bankers and governments, and due to the ease at which traditional money is printed slowly loses its value. Many banks operate on ‘fractional reserve banking’, where they only have a supply of cash at any one time for a certain percentage of customers at once, if all customers attempted to withdraw their money at once, the bank would fail.

Bitcoin is a currency derived from a very large network of anonymous agents, all undertaking a collaborative cryptographic process on their computers known as mining.

Most ledger technologies are physical and they’re centralized -- they’re controlled by a central bank.  This means that they are subject to the discretion and power of individuals, and are alterable and impermanent.

If you own a bitcoin, what you actually control is a secret digital key you can use to prove to anyone on the network that a certain amount of bitcoin is yours.

There will never be more than 21 million coins. This feature makes bitcoin supply almost perfectly inelastic. No matter how high the price rises, miners will not ultimately produce any more than the prescribed amount. Moreover, price rises will not even necessarily incentivize a more rapid mining of bitcoin.

Bitcoin offers an efficient means of transferring money over the internet and is controlled by a decentralized network with a transparent set of rules, thus presenting an alternative to central bank controlled fiat money.
