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.
but where did you got your knowledge ? on other sources too right ? you must give a credit to them and dont say that your already became knowldeagble right after you enter on this business
