Encouraging a beginner to front load his bitcoin investment from the beginning might look a bit unethical for me, the beginning stage for every investor is always the learning stage, and it always has to do with your emotions and your psychological strategy, the beginner can just see a sudden dip and he would panic beyond the normal expectations especially when he has front loaded enough, so for me I would rather advice a beginner to DCA with some level of caution and take out time to understand how the market works, so probably after 2 to 3 years of experience, he/she can then front load his investment, because at this point, he wouldn't easily give in to panic no matter how fluctuating the market price is.
