There are many people who pretend to be crypto experts. Some of them are experts on investing on other markets such as stock, commodities etc., which is nice, but if they just try to apply the same approach for crypto, then their advices can be useless. Crypto market is still too young and there are not many real experts, some people just have more experience and some less. In some cases, the more experienced people pretend to share information and advices, but they are just following their own interests. So it is important to be careful and continuously gather information and knowledge.
