The main purpose of someone investing is for them to get money, no one invests without targeting anything, it doesn't make sense at all. However, what makes the difference is that some have prepared it well from the start, some have not done that and there is also a difference in the capital they bring at the beginning. Everyone has the opportunity to invest, but not everyone can be patient and bear all the risks. Because no matter how promising crypto investment is, it does not mean that investment here is without risk.
Yes, investing certainly has risks that will be faced, and of course expecting a greater return, that is the main goal of investing, but again it all depends on someone to start it, the need for patience is what needs to be applied in investing without it it is difficult to achieve what you want, but we have to focus, especially with crypto investments that require broad insight.
You have a good point, everything has some form of risk associated to it and so does investing too. So, understanding the risk and acting to mitigate them is very important and even one of the most important thing to do in the process of investing. One way I have decided to go about mitigating such risk is to keep the bulk of my investment in Bitcoin alone and just a little fraction in other things. This is because of my trust in Bitcoin which is not going to disappear any time soon like many other cryptocurrency do and cause people to lose their entire fortune.
