I am considering adding ideas from
another post that I made today to the
BTC accumulation portion of this thread.
An attempt at a fair historical overview largely seems to establish that with the passage of time, especially if we look in 4-year increments, it seems to have been becoming more and more difficult to accumulate similar amounts of BTC, even with similar or inflation-adjusted (cost-of-living adjusted) larger amounts of capital.
Edited: This post ties into these accumulation goal ideas in regards to how BTC accumulation goals might change over time, too.
In my opinion, those who are beginners in bitcoin, indeed in investing in btc must be full of calculations because business and life competition is getting tougher, so we must be smart in managing investment strategies in btc.
