This is a good tooic. If not because of business that you have fiat, but holding it is stupidity. If you buy asset, your wealth will grow. Bitcoin is an asset, people buying it makes their wealth to grow as bitcoin has shown since it was created till now.

I think we can mention Microstrategy also.
