162 BTC is certainly worth a lot now. In the past, many people thought that BTC would not be worth this much, and I think if they knew about the current price of BTC, I think they definitely would not have sold it in the past, so the lesson we can learn is that we should not miss the train and don't let there be regrets in the future if we don't have BTC.
In the past, risk is bigger than now and let's revert the time and imagine of a different story. If Bitcoin rose to $10 and dropped to $0 like many altcoins, people who spent their bitcoins for pizzas, watches, iPhone would feel they made good decisions. People who hold bitcoins, did not sell would feel they made bad mistakes.
In my personal opinion, yes, even though investing in BTC is very risky, it would be better to invest in BTC than not.
Because you see risk is smaller than chance to have profit with investment in bitcoin. You are ready to accept risk by seeing chance to get profit is better. Other people think differently than you and see risk is bigger than chance to get profit, they will not invest.
Personal thinking and individual choice, we can not judge who is right and who is wrong because we don't know how Bitcoin will be in future.
