If we zoom out, there were at least two major corrections in the past. One in 2011 when Bitcoin fell from $32 to $2 marking a 94% correction and in 2013-14 where it took over 400 days to correct from ~$1100 to $170, which is 85% fall from the peak then. Compare this to 2018 fall from $19,500 to a low of $5850 is only 70%. This is just to provide a perspective rather than claim that it will go further.
Bitcoin Bottom
After the peak, Bitcoin dropped three times to the zone of 5800 to 6400. That was not surprising considering the parabolic rise in price from ~$1000 to $19,500 in the last year. As mentioned before, this is 70% fall and if we were to look at the historical crashes – both of them followed a parabolic rise – there is still room for correction.

I think that the bottom is actually quite close to the current level. The $6k support has been extremely strong and has essentially been the floor for the past half a year or so. Even though I'm still not completely optimistic on that being the final bottom before the recovery finally takes place, I do believe that the actual bottom will not be below $4-5k, if not just at the $6k level.
This is mostly due to the huge buying demand that we'll see at $4-5k, if prices were to ever get that low. It's also why it's such a good time to accumulate right now, with minimal risk and huge rewards.
I agree with the article in the highlighted parts in particular. This bear market is only a normal occurance in the bitcoin's historical cycles. It's not really anything surprising. A bull market will emerge as soon as the prices bottom and the recovery starts, which I believe will happen before the 2020 halving happens.
