@cryptographic,
I am awaiting to see the seasonal trend! Last time it might start happens June, so I wish it might happen this year again! Anyway, I am always keep in touch with graph to see the price of STEEM and SBD! And some small trades made me profitable as well!
(Sell STEEM in high price and buy in DIP)
Cheers~
I estimate seasonality to be positive into mid-summer.
