We now can clearly see the volume drying up, this is irreversible.
The price is slowly but surely decreasing, from $4.80 to $0.64.
I have to say, Oyster is f*cked.
I'd say that people are waiting for the mainnet release that is scheduled for May 29th (in just 11 days). That's why the volume is decreasing. And for the price... You can't compare ATH price in the beginning of January and the current price. In the beginning of January all crypto was at it's all time high. You can check out any crypto currency and you'll see that it's price is significantly lower now than it was in the beginning of January.
