I totally agree with you.
However an investor who set target of 3BTC in six years mostly be more aggressive than another investor who have no target.
Alot of investors have their accumulation goal, and that same goal may determine how aggressive one need to be in accumulating Bitcoin, at first one don't have to be over aggressive in order to meet his Bitcoin goal expecially an investor with low financial stability. That why the range of holding and accumulating from 4-10 years is a nice one because it would give one enough time to accumulate some good quantity of bitcoin without being over aggressive in his Accumulation. Because when one his being over aggressive with no proper planning and low financial stability, he or she may endup not having an emergency funds in the process because you being too aggressive towards your accumulation, which may lead to one depending on his investment whenever an over whelming expenses hit them which may lead to one having the habit of tampering with his investment.
You're right Mate. I always lay emphasis on the need of having a "TARGET" while accumulating, with a system that will help you achieve that. When it comes to aggressiveness it subjective to everyone how they go about it, which leads to the target set and how the other perceive Bitcoin to be.
Some just accumulate for accumulating sake without any direction or plan. Have a plan with a target, ensure continual investment.
