Antshares / NEO is falling in price a lot. Tell me some theories

I believe most of the price drop is from DIECI, a new coin that is a blockchain killer app..
Here are my theories too:
1. It was a scam all along
2. NEO blockchain does not work
3. NEO is centralized
4. The real price of NEO is $0
5. DIECI's launch
6. People selling of NEO to buy into more advance project (EOS, ETH, DIECI)
I think not only neo but all the crypto coins was decreasing it's valie right now.But the time comes it will increase again.
