$LGCY hasn't been around for too long, or at least most of its social media haven't. As far as I know this coin is only available on Uniswap decentralized Exchange and even then, with very low trading volume.
It claims to be a Dapp based blockchain, so that may be their main usecase. While that is a competitive market, $LGCY is a fork of Tron blockchain and promises it utilises the best parts of Tron, and adds effort to stand out from the crowd by adding more emphasis on community support and the system of governance.
The project uses a dual token system, users would be able to stake $LGCY and earn $LFUEL (gas/utility token for LGCY network), up to 56% APY for locking up their funds for a specified period of time. Its been making moves to secure its market share lately with the community competitions, call for developers to build on the blockchain and the partnership with Unifyre Wallet. In time I see big things are likely to come from $LGCY.
