The most important and primary objective of a crypto enthusiast hoping to start an investment would be to the acquisition of cryptocurrency basic knowledge and as you've rightly stated, there'll be opportunities to acquire advanced knowledge as they advance further.
But then again, when/if an enthusiast moves further to acquire advanced knowledge of Crypto before deciding to venture or begin building his portfolio, he then gets an edge and added advantage over the investor who begins with just a basic knowledge, he then has the advantage of avoiding some minor mistakes that newbies ordinarily falls into in the course of learning.
I'm not saying they won't bump into mistakes or that those mistakes are bad, no, most of these mistakes often create the best learning environment for the newbies and whatever experience or knowledge they receive from such mistakes would carry them through their bitcoin journey.
But there are some mistakes that, while newbies learn from them and use those experiences in the future, those mistakes could cause them major setbacks that'll take them time to be able to recover from the impact, and some don't even recover at all, but by first acquiring both basic and advanced knowledge of bitcoin and cryptocurrency at large, some of these mistakes could be avoided.
