NEO is a popular chinese cryptocurrency that resembles ethereum. Neo just recently passed $100 for the first time ever. Something important to note is that NEO actually pays dividends to NEO holders. This is in the form of GAS (a crypto currency used to pay for transaction fees). If you own some NEO, you're better off holding it in a wallet to generate GAS. Note that wallets only hold full NEOs.
tl;dr
- Holding NEO generates GAS
- Exchanges keep this GAS for themselves
- Wallets can only hold full NEO, no fractions
