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.
"What we do here on a daily basis" - Don't claim to know the financial affairs of everyone here. There are some people who are dirt poor and in debt, trying anything to find a way out but having no funds at all to start. A small group of people will have gotten lucky enough to cash out Bitcoin at the right times (note: converted to fiat) and are living a very comfortable life right now. There are others who come here out of curiosity, to keep up to date with crypto news but have their investments held in other places. It's simply a ridiculous and mindless philosophy to "hold forever" because people need fiat currency to live in the real world, you must convert it to enjoy any potential gains. Plenty of people keep money in the stock market which has beaten inflation over the long term and will also be a method of support.
