For sure, I would like to point out that historically bitcoin has had compounding effects over each cycle and also even more compounding effects over several cycles, yet I would like to also assert that compounding effects are not guaranteed merely because a person stays invested in bitcoin for more than one whole cycle. 

There is always a risk that bitcoin might not go up in value and even that it could go down or go to zero, so even though many of us appreciate that bitcoin seems to continue to have one of the best investment theses, even perhaps the best, it still is not guaranteed to go up, and I think part of the reason regarding having an investment timeline that is 4-10 years or longer is to make sure that you are considering bitcoin as a long term investment rather than merely trying to trade waves, and sure everyone is free to do what they like in terms of their approach to an investment, even though there are probably plenty of us who would consider that you are not investing in bitcoin if you cannot at least come to it with a minimum of a 4-year investment time line... and yeah, maybe when I came into bitcoin in late 2013, it might have had been more difficult to actually commit to at least a 4-year investment timeline since bitcoin was ONLY less than 5 years old at that time in terms of how long it had been running, and maybe only 3.5 years or even less in terms of having (and growing) some kind of a market price.

So various bear case scenarios should also be included in terms of any thoughts to get into bitcoin and to build a bitcoin stash, and are non-bullish cases are not eliminated merely because the timeline is longer... so be careful both in terms of suggesting that compounding value is guaranteed and/or that negative scenarios (or less bullish scenarios) are no longer applicable, merely because you choose a longer investment timeline, whether that is 4-10 years or even longer than that.
