when you fund your crypto that's when trading begin, you could not buy or sell without funding your wallet. when you fund it is then you can navigate to any coin you want to buy, you can have knowledge of trading but no funds.your knowledge become useless because nothing to start with.
Once there are funds, courage in starting is also needed in this case because there are some people who already have funds and knowledge, but do not have the courage to start. So it's not just funds that are important here, but also the courage to try it so that it can run as previously planned, although the considerations must also be based on mature knowledge. And I think for now it is very good to start because considering that most of the cryptocurrencies on the market are experiencing price corrections.
