**Good to know:** As the pioneer of the House2e concept, Group Room has built a house-based bank in the web3.0 era. Using real real estate as the bottom line of digital currency, it is the first to create a digital currency investment entity solution, which perfectly combines the security of real estate with the high liquidity and high yield of digital currency. Investors enjoy the property as a guaranteed minimum value while earning high returns from the appreciation of GRM.
