I kinda agree with his prediction (despite the fact that he is a "bear" and he is dying to see a lower bitcoin price).The true bottom will be around 2-3K USD and any new ATH will happen after the next 2020 halving.
It takes a lot of time to build some new hype around bitcoin.The market is insecure and the fear dominates over the greed.
Sure, when you look at a BTC chart and the last year or so, to say a bottom is in is way premature. Tone is clearly a Bitcoin maximalist, but that said, he sure isn't a perma-bull. His 9 count candle method (which I don't yet grasp - haven't studied it) appears fairly accurate. Anyway, I myself can see BTC coming back to 2500 USD but lots of factors are in play.(e.g. Venezuela - real world problems guys!).
I would NOT just be sitting in cash in these times. Having been through these "Bitcoin bubbles" before, you know when the true despair sets in and I'm not really sure we've hit that. Regardless, unless you are just going to hoddle, don't put all your eggs in one basket time wise (i.e. calling an end to a bear, bottom, etc.) Bitcoin moves really quick going up, don't get lost waiting for a bottom.
I "listen" to a lot of opinions on Bitcoin, don't hold any of them, but take them into account along with what my TA/mind see's. Alessio is nice to watch btw on Youtube...
