What is happening with value 

Probably the last bit of the Whales group exiting the coin as they move on to other coins. That or someone has intent to damage the coin price. We do have haters. Once either or both are done the price will go back up a bit. It is a good buy chance imho.
lol dev you just unintentionally triggered a panic sell down to 4.5k and maybe even lower.
saying that whales have exited a coin is not smart. everyone knows you need whales to pump a coin.
