If you're still primarily holding fiat, you're not paying attention to what we do here on a daily basis. Inflation, according to Elon Musk, is the most regressive of all the tasks. The US dollar has been the strongest currency for the past 100 years, yet it has lost 95% of its purchasing value since 1913. Fiat currency will always lose value over time, but cryptocurrency will always gain value over time; the two are moving in different directions. According to recent studies, 40% of all US dollars in circulation were printed in the last twelve months. Every day, they are printing away our wealth. Opt out and invest in cryptocurrency instead.
The first thing you must understand is that there are quite a lot of crypto's, some of them are shitcoins, pump and dump coins, coins without any use case whatsoever, etc, thus many of them are not even in any way worth hodling whatsoever, having said that, I know there is Bitcoin that can serve as a hedge to Inflation, and as far as I'm concerned it's somewhat one of the very few coins that's actually great to hodl as a currency, hedge to inflation, investment, etc.
When i used the word "cryptocurrency" I didn't mean cryptocurrencies in general, I already know that most crypto coins and tokens are scams, some fake and others rug pools.
But what I expect of me, you and every one else is to know the right cryptocurrency to invest in that will guarantee profit at the end of a certain period like every year or maybe 6 months.
One way to know that fiat are useless is to keep $100 usd in fiat and buy $100 usd worth of the right crypto coin(it must not always be bitcoin, there are several other very legitimate cryptos out there), now, give both 10 years.
In 10 years time, your $100 usd in fiat can not by you a car(under no circumstances will it) but your $100 usd in the right crypto coin has a very high chance of buying you a car (might not be your dream car but it sure can buy you a car).
