Only invest what you can afford to lose.
Cryptocurrencies are one of the more volatile and high risk asset classes that can be invested in and so you should only invest what you're willing to lose. We would suggest developing a personal investment plan where you identify the level of risk you're willing to take along your target returns from your investment. One of the biggest mistakes made by people new to cryptocurrency is lack of planning around their investments.
Investments in cryptocurrency should be part of your overall investment plan. Diversification helps protect you against sudden changes in any particular market.
