Republic Protocol is a decentralized exchange which utilizes a dark pool. This is similar to OTC trading used by other financial institutions, and it provides vastly superior liquidity for high volume traders and private transactions. Both of which are prime concerns for high volume cryptocurrency investors. The REN platform also utilizes cross chain liquidity by enabling atomic swaps.
The project is backed by many high profile investment firms, and investors in the project will have the ability to earn income by running what is known as a dark node. These nodes secure the network and process the transactions, and those who host the nodes could benefit greatly by way of a new monthly income stream. If you're interested in a Republic Protocol investment node you'll need around 100,000 tokens.
There's a number of exchanges available upon which potential investors can buy Republic Protocol. Some of them may be a little foreign to some investors, but there's plenty of trading volume here to support a trade. Bitcoin and Ethereum are the most viable trading pairs here, as they control the bulk of the trading volume. However, there's also some activity in the US Dollar Tether pairing if you'd prefer to utilize that instead.
This is an Ethereum asset, and that means you need a wallet that can store ERC20 tokens in order to keep your investment secure. Never store assets on an exchange, as you don't own the wallet. That could make it difficult for you to reclaim your funds should anything happen. Instead, utilize a private wallet option such as Meta Mask or a hardware wallet like Ledger.
