You must set goals. What do you want to achieve for the money that you will be investing? Is safety of your investment with some level of return sufficient? Are you trying to grow your money for a longer-term goal? You will even have different types of investments for different goals. Before you decide to invest any money into cryptocurrency it is imperative that you understand why you are investing and the result that you desire. Goals should never be created in a vacuum. You also need to know your risk tolerance and your time-line as part of the goal-setting process.
I agree with this, some people just pay attention to people who already success in cryptocurrency without knowing what cryptocurrency is.
Risk can mean a lot of things. Investing in cryptocurrency means you have a risk of losing money. Your money invested can decrease in value, possibly to zero. ALL investing involves risk in one way or another. Stocks often can go down in value over periods of time, just like crypto. Do you remember what happened in 2008? The S&P 500 dropped by 37%. This decline in the stock market was one of the worst in history. Severe market corrections are not uncommon, especially in cryptocurrency!
Risk is commong thing you will get when you do investment, so knowing the risk from their investment place is first thing they should do before trusting their money in there.
