That is definitely happen but how low do they want the price to go? The price is still below 4000 dollars which means that you are only paying one fifth of the highest price bitcoin ever reached, the price cannot get that much better, so the people trying that strategy should stop their efforts to keep crashing the price and instead should concentrate themselves on accumulating as many coins as it is possible for them because even if it took bitcoin a few years to reach that price again they will still get four times their investment during that time.
It's hard to act on accumulating since the market is pretty much unsure and maybe the best thing we can do by now is to research and study the market so that we can earn without being trap on the highest price reach by the bitcoin these days.
You only need two things to start accumulating coins, one is money and the other is the guts to buy bitcoin and hold it long enough to see profits, in my opinion that is not hard at all, it is true that the market is not growing but if you wait until the recovery is clear for everyone then it is likely that you will buy your coins when it is too late and we are close to the top so you will get almost no profits or even some small losses, remember, the whole point of accumulating coins is to begin to do it when the price is still low.
