It's a fallacy to think that unrealized losses don't matter, regardless if you talk about Bitcoin or altcoins. There's absolutely no guarantee that if you wait long enough, you will break even. You are right that altcoins have way worse chances of recovering than Bitcoin. But nobody should put all their money into Bitcoin and think that it's a risk-free strategy to get rich.
All investments have their own risks, some only manage to lessen the risk because they start investing with sufficient capital, knowledge and skills, compared to those who jump to investments without prior preparation. And bitcoin is not an exception. Yes, it’s the most profitable asset and the most prominent crypto coin, but that won’t lose the fact that bitcoin is still a very risky investment because it’s highly volatile and it’s price movement is very unpredictable. However, I would still invest in bitcoin with caution than to entrust my funds investing in meme coins.
