Hey, are there any new active exchanges, the price is high
Not that I know of. Price can go up and down immediately because there is no liquidity.
Maybe they are doing little buyback.
Doing buyback without informing anyone? I really doubt it. But the liquidity part sounds more plausible.
Did they inform us before or after the first buyback? Personally I wait anything from this team

How can they do the buy back if they do not have a good exchange, and the timing is not really good for them because the market is red.
If they will do a buy back, they will make an announcement prior to that because that is the standard procedure.
