Well, if crypto is here to stay for good... DOGE in 2020 could be a $1. But I don't think anyone is thinking that far ahead.

My investment plan extends between 5-10 years. I don't know where the market will end up, but by planning years ahead rather than weeks or months I am not at all concerned about short-term crashes, or missing out on short-term gains.
For those who do not have the personality type to speculate short-term or daytrade a long-term investment strategy may be a better strategy for an irrational market.
i'm not saying everyone needs to think that far ahead, but sometimes it helps to put a different perspective on what's happening right now. the long view has certainly kept me out of altcoin-of-the-weeks, and i've reconfigured my coin portfolio to reflect a long-term strategy.
