Any crypto having a kill switch is rather far-fetched. Why did they have it in the first place? Any centralised project can have a lot of things their way or unconventional but when I read about the whole project going off-line for those two days or so it shows exactly why IOTA should and any other centralised crypto should be avoided unless they show exactly what cards they are holding.
Back in January 2018 this project had a market capital of over $14 billion but IOTA now has just $770 million market capital and it is dropping fast. Here is yet another of many mismanaged projects that had too much talk and not enough action and development therefore it fell from massive all time highs to a fraction of that.
