Art obviously doesn't know how to read a log chart, or doesn't care.
On a log chart, Bitcoin doesn't currently look parabolic.
It absolutely looks parabolic on the weekly log chart. A parabolic structure isn't just the vertical (blow off) top, it's the entire run-up. The curve into vertical ascension is unmistakable at this point. We haven't gone
vertical on the weekly yet, but we're likely only to get one or three candle closes at that point before the blow off occurs.
$50k/btc within 3-5 months from now would be parabolic. I don't see that happening. And if it did, I would be agreeing with Art then.
The difference between $10k and $20k is a matter of days at this point, literally. At this rate, we'll get to $50k much, much faster than 3-5 months. I suspect this rally will break down before we get to that point, though.
