Aggressive buying, provided the newbie is full of knowledge and ready to hold for long time, I would not discouraged such buying because most time the starting of investment may seen lumps sum and if what leads to that level of agreesive buying crackdown one can stick to any of the strategy that suit it's income because money inflow most time is not the same to hold and avoid buying aggressively when is available is of more risky because unplanned can take the money where regret become the order of the day. I remember my first buying of a token which I was holding at a start I bought heavy after a while my expectations cut off I need buy not exact quantity but drop to gradual accumulating.
For beginners, it's actually better not to make aggressive purchases, especially for the first purchase or the few purchases that follow. The concern is the inability of beginners to control their emotions, which can easily disrupt the initial investment plan. We know that because of the excitement in investing, sometimes we also allocate more, especially when the market is in a bullish trend. Beginners often fall into FOMO.
I think this is true for many crypto investors, not just beginners.
It is very important to analyze the market well before each investment, and make a specific investment plan, and a clear exit strategy.
It is also very important to learn to control your emotions because we all have some plans at the beginning and how much $$ we would be happy with, but when the cycle of rapid growth in the price of bitcoin starts, emotions become stronger than reason and we deviate from our previous plans (carried away by euphoria), which usually ends badly when the trend changes and the price of bitcoin suddenly drops.
I know many friends who lost a lot of $$$ because they did not follow their plan but became euphoric and wanted more profit.
