the risk that can be obtained of the three is the crypto market which goes down and makes the market chaotic. other than that someone who invests or trades shitcoin will certainly get the losses and will get nothing so before investing into crypto we must be more careful in choosing the coins. The coin that we choose will also have an impact on the profit we can get, invest and trade the coins that do have good prospects.
Why anticipating loss already by trading or investing those type of coins? There are investors and traders that are making a lot of money from trading those.
It's that it's not ideal for us because they're not our choice. But to them, they're making a lot of money from it when they get to ride the hype at the beginning of it.
For me, Cryptocurrency trading and Investments are mostly about knowledge and some level of luck. You might be right when you said, people are making money from investing in some type of cryptos, a lot of other traders have lost money from those too so it wasn't because they knew it was a better option but just took a higher Risk = Higher reward.
