Yeah, what's so scary about the down turn? this is just a normal correction. $17k was retested, just rejected, the price support at $16500 but then didn't hold goes down below $16k, that's how the market moves.
Scary is when the price goes down -60% last March and everyone has bitching around saying that bitcoin is dead, Lol. Much better to just stay relax and let the market goes on it's normal flow. We are not yet in the bull run that we are looking like the 2017, the four year cycle begins in 2021 so we have a lot of leg room to make for a new all time high next year.
Gainers are selling their profits and now they are back in action bringing the price to rise up again, it's a normal to see as we are inside trading business, no need to be afraid. You have to condition yourself that with lots of chances this traders will continue to play, be wise and make your own assessment market will continue both sides are possible you have to position yourslef and make sure to have a good back up plans in case thnigs won't og according to your first position.
There's enough time as you mentioned, if history will repeat itself then not just $17k but it can go more, if things went smoothly we might
see another ATH, who knows right.
