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)
7. The whole market fell. NEO isn't an exception, it just fell along with everything else. It's still a good project, I still hold some, and I expect it to rise again.
