also with the announcement of paypal also beginning to offer such service to its existing user base and half of the service rate will force many in the sector to revise, downgrade their forecasts and expectations which also throw the timing of a market top with a cool off trigger then the short will be on imo!
although I am completely out of the market atm, I wont be shorting or playing much this year due to personal reasons and circumstances.
good luck with that one though I wish everyone all the best regardless of stock, sector, instrument or market.
