Or just remember how volatile the market is, at any moment, the price can go down very hard, double digits and it will take some time to bounce from that. Or thinking that we are still in the bear market, so anything goes, just one negative news will affect the market.
It's better to anticipate things, we have to think ahead of the game. If the price goes down and reaches $15k, don't be negative, treat it as another opportunity to stash again.
If the market didn't reach any lower lows again before the eventual bull run for next year, still continue to accumulate and do DCA, win-win situation for us.
