The crypto market has an high level of volatility, anyone who is about to make an investment need to have a good understanding of the volatile market. Now the question is even with the volatility will you still choose crypto over fiat when it comes to making investments?
The key for success is absence of radicalism and unhealthy enthusiasm. Investor thinks about wealth in general, keep wealth in long term helps diversification, what means that investments should be done in different industries, in different currencies, with different APY. Therefore, I would consider option of investing in crypto (by using USD as currency which will be used to calculate profits), add to this investments in precious metals, investments in different strong currencies (USD, EUR, CHF etc.) plus investments in stock market (to have a share of real businesses). Keeping all money (better say income) in fiat or in crypto - is stupid. Everything needs balance. My opinion.
P.S. Also is important to teach yourself to respect fiat in someway, because keeping part of income in high liquid and mass-adopted tool (currency) is very imported to be able to exist, because not always assets can be turned into the cash to pay for goods and services. Plus no one wants to sell good assets during bear market to cover the costs.
