Its not like that the dump is intentional but there might have got some serious issue with crypto currency like DeepOnion. I did hear the rumours that this coin was scam in the later stages and thus it could be just that people are trying to save their ass with whatever money they get back from the investment that they had made into this coin. Its just the case that they will never trust it again and with mass dump it always starts another panic sell too. So those who aren't aware of the scam will eventually sell due to tremendous dump hype.

Offf course everything here is weird and you cant do anything about it.
