BGX is using a double-token-coin system.

The DEC is the ERC-20 token. It will be traded on exchanges and available for investors. It will be required for node operators to open a node and every DEC token held by a node will have the right to emit and process a certain number of BGT coins.

The BGT coins are the ones actually used for the platform transactions. While DEC is volatile (being traded on an open exchange market), the BGT coins will always be worth $0.10 USD each, minimizing the effect of inflation.

This way, investors get a high-growth token with limited supply, demand pressure from nodes, and tradeability on exchanges. Consumers are protected from crypto-volatility by using the BGT coin. And since nodes possess DEC, each dubious transaction gets dropped down to Ethereum miners to verify, thus adding an extra layer of security.
