An intelligent cryptocurrency investor would always research and study the market before purchasing any coins. They smartly speculate about the upcoming trend and hypothesize about the happening of current events which is a factor in its price movement
I'm not sure what being intelligent actually refers to here
For example, you basically say that people who bought in late 2017 were not intelligent investors, but we know that only in hindsight (remember, everyone is wise after the event). With that said, how do we really know if today's prices are going to explode and not in fact crash a few times again in the coming months? So how can researching and studying the market help for real if the whole shebang is still mostly about gambling and just hopes (likely futile)?
