Investment should always be considered because any coin can be reduced when news comes out.
not all coins are going to decreased thier value on every news that goes out but it depends . good news usually have a good effect on the value but bad does have a bad effect too . that is why investment isnt considered or necessary but you shall only invest if your free from financial issues or debts .
I always use all my knowledge to research and this has helped me to minimize a lot of investment risks.
using our basic knowledge to search for more knowledge based on our investment is a must for every investors . this can also avoid you to loose more than your expectation of minimizing your risk
