do you think next market circle comes on june / july ? for Sia two good market circles has happened. one was July 2017 and December 2017. my prediction is next july ? 
The circles at this market are determined by the combination of key events such as BTC fork at 1 Aug 2017, the Japan government statement about crypto at 1 Apr 2017 and so on. So I think it's pretty unpredictable thing when the next shark make a statement or so on. The only thing I know is that more and more people are coming to this market and due to deflate nature of crypto it can't fall in the long term.
