* **Bitcoin**:  Bitcoin is the world’s first and largest pure cryptocurrency
* **Ether**:  Ether is the native token of the smart contract platform Ethereum.  It can be thought of as a form of “programmable money” (e.g. it can be coded to perform functions such as automatically repay loans, hold funds in escrow, automatically execute contracts, etc…)
* **Stablecoins**:  Stablecoins are cryptocurrencies pegged to the value of fiat currencies such as the Dollar, Euro, Renminbi or Yen
