May projects work towards the hopefully eventual release of their mainnet. Mainnet is generally when the core of the project is officially up and running on the correct blockchain with the correct moving pieces.
Theta recently announced that Mainnet 3.0 would be coming in late June. Citing that; great progress has been made toward the release of Elite Edge Nodes and TFUEL staking and burning on mainnet.
If you were one of the early hodlers of Theta, we salute you! Congrats to all your “Thetans”.
