there is a fundamental misconception in your analysis that miners dump the coins they mine on exchanges, effectively putting pressure on the price.
[...]
First off, I never talked about coins being dumped on exchanges. Maybe you are mistaking me for someone else? Also, my assertion still stands that a continuously watered down supply side increases downward pressure on the price, and I see no use in arguing that. Maybe your position is that there is no intersection between the OTC market and exchanges, but I have no reason to believe that this is actually the case. Actually, one obvious counter-example I can spontaneously think of would be the user "loaded", who is participating both in the OTC market and on the exchanges.
Second, I am doubtful that large industrial-scale mining operations engage in the speculation business on top of their main (mining) business. They most likely have massive regular expenses for employees, electricity, rent and of course for new hardware in order to stay competitive in the race for a large slice of the hash rate pie. I'd say this indicates that a certain amount of coins has to be sold in order to keep the operations running. And even if they are engaging in speculation - this just means that another failed attempt at a sustained rally will force them to sell a bunch of their held-back coins as soon as they realize that new buyers are not coming in to carry the rally further. So, that gives me one more reason why I suspect this current rally to fail spectacularly once the bulls run out of steam and momentum begins to decline.
Third, you are arguing on the basis of a rally that has not materialized yet. All I see right now is an insignificant bounce that hardly registers on the 2y chart, which may or may not develop into something bigger. Which brings me back to my initial posting, where I suggest that the bullish sentiment is irrational at the moment: We just crashed from the worryingly low sub-400 levels to the shockingly low sub-300 levels. Not too long ago the vast majority here seemed to be convinced that we would never revisit such low prices again. Now we FINALLY had the first significant bounce after going down ~$400 all the way from $660 since this summer, but we are still struggling to even break back above $400. This does not seem very bullish to me, in fact I find it quite worrisome.
Also, we had a similar high-volume bounce situation back in march, right before the failed summer rally that couldn't carry itself beyond the $660 point, despite the bulls being immensely euphoric and going all in (as indicated by the all time high in the number of usd-swaps on finex). I don't see why it should turn out any different this time. A high volume bounce obviously does not guarantee a sustainable rally afterwards, but this seems to be the bulls' main argument for why the bear market is now supposedly behind us.
