I often encounter beginners who think that cryptocurrencies, especially Bitcoin can generate significant profits quickly, but this isn't the case. They should understand that investing takes time, managing a portfolio to grow it, making gradual investment repayments, or using a Dollar Cost Averaging (DCA) strategy, so they can see the long-term benefits of their investment. By the way, portfolio management is the important one, especially for beginners, it is best to manage it with money that you can truly guarantee you can hold for the long term, so it is best to avoid using it altogether, and using discretionary income is also the same. Alternatively, you could allocate your fiat savings to Bitcoin, but I don't recommend investing in altcoins, as there are so many considerations and risks on it.
A friend who just moved to a Western country told me how he desperately needs another source of income because the bills in the country were becoming unbearable. He has to keep working so hard that he doesn't have time for his family. He told me that he wants to start investing in Bitcoin as an alternative source of income. My response was simple, let him start another business and forget investing in Bitcoin. If you cannot be patient to hodl your coin for a minimum of four years before selling, investing in Bitcoin might not be profitable. Anyone who sees Bitcoin as a get rich quich scheme will be highly disappointed when it enters the bear market.
