Many beginners really will not pay attention to the good advice of experienced members of the forum, because they come to the forum to get big money in a short time. Only after they are defeated in their own experience will they listen more to valuable advice.
Beginners tend to rush things and they are mostly wanting to get some big profits in a short span of time like you have said and indeed once they experienced things here inside the crypto world they will eventually realize the importance of those points that the OP said. And i think this is really happening, that newbies are really rushing things and it is rare to see newbies that do not rush things and carefully searching things that can help them in their investments, i hope this should be a guide for all of us.
