Where do you see a 40% loss? Ardor has a pretty stable and even slightly growing price in the last week (green line, the daily average price grew about ~5-10%).

The only thing you could criticize is that it didn't move up as fast as Bitcoin, but that is pretty normal - when Bitcoin strongly moves up, Altcoins usually move up slower, with exceptions when one altcoin (like LTC in the past days) is pumped. The moment when altcoins like Ardor can grow compared to Bitcoin's price is when Bitcoin's price stabilizes a bit.

PS: OK, I see now what you're referring to. HitBTC seems to have had a much higher price than the rest of the exchanges and now it dropped to the "mean Ardor price". Maybe they enabled deposits? That would be a good sign - it means that more weak hands are shaken out
