After the lease,
i receive some wavesGo and miner rewards. May i know what is difference between those two.
And one more question, after receive the token do i need to make a new lease of does my previous lease is still applicable?
The lease is sill valid, you don't need to do anything.
MRT is a token issued by waves you cab keep it or sell it in the exchanges
WGO is the token issues by WavesGo and you can also keep it or sell it. More info:
