well if you are not a trader then why are you even asking these questions? just buy and hold. come back in long term and enjoy the big profit.
if you are a trader then asking these silly questions won't help you. if you see price is not recovering and falling then just adjust your strategy to match the new trend. and i am not just talking about now. this happens each time the trend changes!
market is not always going to stay the same, it has ups and downs and sideways and ... for each of these trends you need a specific strategy. you can't just apply one thing to all of them.
You're entirely right, but it's still important to try and understand why the trend has changed and speculate as to when it might reverse. Or else you might be that guy who reverts their strategy to fit the bear trend and sells all their coins at the bottom. If you take your time to understand why the trend has reversed and don't see any reason why it will revert back to bullish (in this case) then it's time to change your approach.
