Everytime Bitcoin price drops, there is always buying up for the price to reach a new high.
Everyone might be used to this pattern by buying the dips at every new high lows form without minding the risk with the hope of always bouncing back.
What will happen is that there will be a lot of people that will buy at every high intervals and could lead to a big market correction where people will be forced to sell at loss.
No one knows when this will happen , but the fact is people that bought high will get tired after several wait for the bounce back to happen which will lead to sell off to cut loss.
There has been more than two bounce back recently that lead to new price but now a trend line has been broken. This calls for a big caution. Market could go deeper or higher. Let's remember BTC has a mind of its own.
Trade safely .
Your case scenario will be true only if 100% of the buyers are buying Bitcoin and waiting for short term profits.Which isn't the case.I think that most of the buyers buy BTC with intentions to HODL for the long term.Only the bad traders sell at a loss.If the price is going down,they will just HODL and wait for a new bull run.This includes the people,who bought BTC at ATH price back in December 2017.I'm sure that most of them will wait for years,so the price could go close to 15K USD,so they could sell.
