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 ? 
Is that you mean the next circle is the blooming or pumping of altcoins in crypto market ?maybe if we base on the data last year,the pick season of pumping the value of altcoin is coming from july to august ,but we always know that this happen of dropping of value price of bitcoin now all atcoins also affected,so by this means altcoins always go with the flow in bitcoin,if the bitcoin will pump the altcoins also will grow and if bitcoin is dump same happen also into altcoin value all will go down.
