Nobody explains how and why he chose a coin. Therefore, my assumption is that everyone risks investing in crypto and hopes that sometime good luck will come to them)
Why do you think that no one will ever explain how and why he chooses a coin to buy? On the contrary, on the forum you can find many posts where traders describe which coins and why they buy. There is no secret in this.
Sometimes traders don't say which coins they buy just because they dont want to impose their opinions on anyone and influence a persons choice. But this is completely different and here it is already necessary to understand what purpose a person has in asking such a question. Plus, an experienced trader when choosing a coin relies on a certain strategy and, for example, a novice will simply not be able to trade this strategy due to lack of knowledge and experience. Therefore, it makes no sense to talk about such coins with a newcomer.
