The bigger the risk, the bigger the gain. If anybody is afraid of losing then put the money in a bank or in a vault no risk no gain. Take the risk if you succeed you will be happy if you lose you will become wise. it's a win win situation. But offcourse it defends on how you absorb the situation.
Right you are. Profit is the reward for bearing risk. Any investment is risky because it may generate profit or incur loss. To make profit you must accept risk and face challenges. To make big profit in coin market, you have to go through outlier challenging as well as risky coins.
Risk is huge, the profit was also huge. Now I am pretty unsure as the days are becoming unstable in crypto market. But still new ICOs and few coins have future prospects with growth, which would be decent one. But usually in all sector related to earning/profit, risk bearing capability and risk taking is necessary.
