How much cryptocurrency you should buy depends on your goals, risk tolerance, and level of interest in the crypto market. Never spend more money on cryptocurrency than you are willing to lose. The cryptocurrency market is risky because digital assets are speculative. There is the potential for significant gains, but there is also the risk you could lose your investment. If you are new to cryptocurrency, most financial professionals advise investing 1-4% of your portfolio depending on your experience and comfort level in the market. However, this is just a general rule of thumb. Only you can decide how much cryptocurrency is right for you, based on your risk tolerance.
