There are one huge dumper who solomine on two wallets.
And almost every day he dumps tens and hundreds of thousands of Aro coins on the exchangehe. It's creates huge pressure on the coin price.

You can find his previous deposits to Octaex exchange from these two wallets to an account with nickname Zean9400.
Also, during past 100 blocks #57473-57572 (as of time of writing this post) he found 44 blocks, that's means that his hashrate is about 100Kh/s. While total hash rate of all public pools - Aropool.com, aro.cool, aro.party and arionum.rocks is about 105+4+25+2=136Kh/s
It's impossible to deploy such huge amount of aws, gcp  instances to achieve 100 Kh/s on arionum network.
I'm doubt that he is legit miner and not any kind of botnet or something like that.
This  means that an unknown person is controls almost the same hashrate as all miners on all public pools - it's about 610 miners
Don't think that this is a healthy situation for Arionum coin.
