Actually it is simple. It was overhyped beyond belief which makes every smart investor sceptical in the first place. Nice brand, nice design, but technologically not so advanced until today. Undeserved high market cap of 1.7b at start. Now the hype continues to wear off until it reaches bottom. Could be still some weeks until you see an upwards trend and I would not suggest to buy anything before that. The initial investors who accumulated in the last months already sold or are still selling everything they have because they speculated on a nice ROI when IOTA finally hit an exchange. I would strongly advise against buying in larger quantities at this moment. Just be patient and see how it develops or just take your chances with a great risk.
I agree with you, And most importantly they are yet to fully disclose how their network is secured, POW alone cannot secure it as very little hashing is being done.Their POW is scaling only with the transaction rate, in other blockchains it scales with the block reward but here it does not apply.
