It's true, it's also how we use Bitcoin in the past. Pay with Bitcoin in places that accept Bitcoin or hoard it as an investment.
The truth is that many people have gotten rich by hoarding Bitcoins in the past.
If people got rich by hoarding in the past then we just follow the same thing, we are hoarding bitcoin now then 5 or 10 years from now to be rich, but I'm sure few people dare to do this, most people will always say its too late and no dare to take risks.
