4/22 of the people participating in the poll still seem pretty sure that $17.7K is a low point. While the other 15 are still thinking about other lows (myself included). Although since hitting $17.7K we've seen a bit of a price recovery, it's still pretty convincing that another low will be hit so I think the current poll results are pretty reasonable. While the poll won't be of much help, it's just an idea of what traders believe in these volatile market conditions.
When bitcoin hit 17.5$, it cannot go further straight down and there was always a chance of pullback. In event of a market dump, there is always a relief rally. We are seeing the price is hovering between 20-21K for last few days but unable to stay above 22-23K. This means that people are still not confident to buy bitcoin now and perhaps we may see bitcoin dumping again. If this happens, it won't be good for bitcoin and we may see more blood in the market.
It's not that we have seen blood in the market for a long time and for those who are mentally strong to see the price drop to $17, maybe they are used to it since that day bitcoin fell to $17 thousand and they saw the price of bitcoin go up to $20 thousand and I think for now this and the next few months bitcoin will continue to play at the bottom price, which is still around $20 thousand or $21 thousand.
