Investing in bitcoin carries risk due to its volatility. This danger cannot be overlooked or minimised by holding bitcoin for an extended period of time. Holding bitcoin for a long time does not ensure successful returns at the end of the investment period.
Accumulating bitcoin with discretionary income is not only because it does not guarantee profitable returns in the long run; it is also because this money will be locked up for years. As a result, using money intended for our survival to invest in bitcoin is a horrible idea.
Investing in BTC is indeed very risky due to its fluctuating price, and sometimes people lose money by selling BTC below the purchase price. However, this certainly applies to those who enjoy trading BTC, as I know of long-term investors who rarely lose. While long-term investing in BTC does carry risks, we don't know what will happen to BTC in the future. However, if you're not prepared for the risks of investing in BTC, I think it's better not to buy BTC at all.
If you buy BTC with discretionary income, it will certainly make you comfortable because discretionary income is the money left over from your basic needs. Certainly, if you don't use discretionary income to buy BTC, there's the potential for loss.
Bitcoin is a promising investment, particularly as a long-term investment. With its price trending upwards, it stands to reason that it's a long-term investment. Furthermore, Bitcoin is the parent of all its peers. Despite its promising potential, it carries significant risks, and we can't predict when the price will drop. Purchasing Bitcoin with discretionary funds is a wise move, and it's best combined with a DCA strategy.
And if we have a fixed income, then I suggest trying to invest some of it, so that there are funds remaining after meeting needs, or what is usually called discretionary funds.
