You said it right but the problem starts when the investor is too emotional and thinks that this is still not the right time to buy. And that is because there will be a lower price than they have to wait before everything increases.
The bear market is there to give us the chance to buy as many altcoins as we can but people do forget that it's also the time to get more bitcoins while it's cheaper than what it has achieved for its all time high. That's always being forgotten because everyone seems to be focused on alts gain.
