When you are still a newbie to this cryptocurrency world, it is better to take action and study the flow of its ecosystem and be prepared when you make an investment to avoid a profit loss. Don't make drastic move that you didn't prepare to it. Always make your own research first.
yes of course I agree with you that knowledge is really needed before we decide which investment to invest in. and I think we need knowledge in all things not only in investing in cryptocurrency. we must learn to understand this before doing so that what we do is not wrong.
and in cryptocurrency we have to read a lot about the characteristics and movements of coin values because currently the number of crypto coins is very large. so do some research before investing.
