I'm sure they wouldn't play with community like that. Wait for further announcement.
I also replenished my wallet using https://rhino.fi but in the sequel, I just translated Manta into Binance. But I have not made a final decision whether to sell the coins now or wait for the price to increase.
I stopped using CEXes as they require KYC, also there are some regulatory troubles accessing CEXes in my country these days, so I prefer not using them.
Better hold or stake if you accumulate enough $MANTA to stake, as there are going to be airdrops for $MANTA holders and stakers, read here. I sold portion of airdrop received and holding rest.
