Hodlers are those who have enough, bitcoin BTC is money and not a property unless you don't have bills to pay. I receive, I spend, I buy, I repeat again.
What would you gain If you hodl all your bitcoins and die the next day? Nothing. You only cause scarcity which increases the price of Bitcoin BTC... That's a win-win for bitcoin.
For a moment forget about bitcoin or fiat. People keep on hold and save money for the future and while doing so they exclude that they are going to die one day or next day. if people start thinking about this, everyone would spend money, help the needy one and the world would be a better place. But this is not what is happening in reaily.
Now, since people save money (Fiat), they save bitcoin too but advantage of keeping bitcoin over fiat is that bitcoin will gain value over time while fiat will lose value over time.
So if you hold bitcoin and forget about the death ( Not spend the winning amount in art contest), you could have gained much more. The reason i pointed out was that people don't visualize the future and think that if they cash out at 50,000K, they are in profit while they could have waited to cash out in 2025 at perhaps 1,000,000$.
