godo while some suggest that this is the end and the bubble will burst soon there does not seem to be a technical pattern that indicates this is the case. Having been a technical trader for over 40 years I am always looking for a technical indication / pattern that indicates a top. The charts are ones best guide for determining an exit scenario. I will continue to keep a vigilant eye on them for the signal.
One other note as far as the canary goes. With the opening of futures markets in this space the number of potential new participants to BTC , always the headline crypto, is significantly increased. Some will sell but I expect there are just as many or more interested that will buy. FCM's will be far more accommodating to buyers as the max downside risk is know at any given time so allowing buy only client access is a good possibility for the small retail type investors.
