"Please don't tell me that you have that much faith in companies share."

It's not so much having more faith in companies than in crypto, as it is in knowing "how" to read the information you have at hand. More often than not, there are many tell-tale signs of a company not being what it is being promoted to be. The real skill is being able to spot those tell-tale signs so as to avoid such companies. Such skills are acquired over time through a combination of knowledge and experience, which is why seasoned investors / traders nearly always make money regardless of the direction of the markets, whereas the newcomer almost always loses his money (or at least fails to make a significant profit) in such ventures. Good luck!
