What do you concern about? Profits or knowledge?
If you focus on knowledge, sure no one will declare he has enough knowledge about crypto. Your feeling is normal, we must be always trying to have more knowledge in crypto. However, if you refer to profits, I assume knowledge doesn't guarantee success in trading or investing. Having sufficient knowledge is only the way to minimize the chance of losing and ensure us trade or invest properly. Regarding success or not, it depends on many factors, including the market situation and how smart we choose the strategy.
Even legendary members here has a lot to learn.
So the OP should not worry because everyday, we are learning.
Even experts are continuously educating themselves.
But would be your advantage if you are willing to learn and try new things to improve your skills.
If you are not applying what you've learned, you won't know how it will impact your life.
So yes, it doesn't mean that the more knowledge you have, will guarantee your success.
