I strongly disagree with the statement that "Without money, the knowledge is a waste". Money can be obtained in various ways, not necessarily in the world of cryptocurrencies, and if you get funds, then you can skillfully use your knowledge. In my country there is a proverb: it is better to lose with a wise man than to find with a fool. I also follow this principle. If your knowledge and skills are really at the right level, you will find a way to earn money on it. If not, your level of knowledge may be lower than you think.
