3 Cryptocurrencies to make money for you during sleep

“If you don’t find a way to make money while you sleep, you will work until you die”.
NEO

NEO is often referred to as "China ethereum " or "ethereum Killer" by many, Neo is the first digital currency encoded decentralized, open source and blockchain platform launched in China. Neo has another coin called GAS (formerly known as ANC-Antcoins).
VeChain

Although still a work in progress, I couldn’t ignore VeChain Thor (VeChain’s pivot & re-branding); a project that has been making waves in the space as of late. VeChain Thor is going to move beyond the supply chain, and into Enterprise Decentralized Application (dApp) solutions. I will not discuss how VeChain currently works, but will focus on VeChain Thor.
VeChain Thor will introduce two new tokens:
-VeChain Tokens (VET) will act as the smart payment currency in order to enable rapid value circulation within the ecosystem based on the VeChain Blockchain. VET represents the right and privilege to occupy and use the public blockchain resources. The more VET one holds, the more rights and higher priority they have (to use the blockchain).
-THOR Power (THOR) will be the fuel on the blockchain and will be consumed/burnt after certain operations are performed, such as transferring VET or executing smart contracts.
ARK

ARK uses a consensus mechanism called Delegated Proof-of-Stake (DPoS). This mechanism requires coin holders to vote for delegates, who are responsible for validating transactions and maintaining the blockchain. It is quite similar to dBFT with the major difference that in DPoS only one delegate verifies the block, whereas in dBFT, 2/3 of the bookkeepers have to reach a consensus and generate new blocks. You can find more details about DPoS and delegates.
