Investing aggressively is not only for the rich people like alone, though they have a strong financial strength that will make them in a situation to buy aggressively than someone with a small discretionary income
You second statement has completed everything and said it all. "Though" means they have the superior power to buy bitcoin massively and that is the aggressive investment. If an investor bought some unit every month as a DCA which is amounting to $500+ monthly, he is not an aggressive investor but a passionate investor. I call him a passionate investor because he has the passion to invest but people like Michael Saylor and Elon Musk can buy bitcoin of $1 billion and this is the aggressive investors JayJuanGee about and not the peasant investors.
