Crypto investing is risky and there is no guarantee of profit every time. So always invest money that you can afford to lose, never borrow money to invest or trade.
Although investing in Bitcoin and holding it for a long time can generally be profitable, we should only invest in cryptocurrencies with money that we can afford to lose to reduce risks and losses.
Man has to conduct his daily or monthly expensive with his own plan. Every month they spend their income in various ways. Those who have more income have more expenses. I think 75 percent of people can't keep separate their income. So I can't say that I have extra money that I can invest. Since many of us don't have that ability, we have to invest in Bitcoin with what we have. What matters is the potential of the investor's invested assets. If Bitcoin is invested and has the ability to hold for a long time then it will not have much effect to use that kind of money for it. Nothing good can ever be achieved without taking risks.
