It doesnt make sense if I can get thousands of staking rewards, but the price plummeted to blackhole.
If this terrible scenario occurs, I will get almost no thing, dramatic losses instead of earnings.
As far as I can tell MWAY isn't traded anywhere anymore - it was only traded on sub-sat market on Cryptohub. I agree with you, it staked well, but the price - such as it was - doesn't exist anymore. Only otc trading between users, if anyone still wants MWAY. If you have significant holdings of MWAY perhaps you should consider the swap to Legion Coin after all - I believe the swap could still be ongoing, see their discord, to salvage what you can.
Here's the ANN thread for Legion coin:
