In trading, making profits is not guaranteed all the time so accumulating for a very long period like 10 years as you stated may not really be an obtainable idea as the future is unpredictable no one knows how the fate of the coin might turn out due to some uncertainty that surrounds the stock coin market. Making accumulation for a very long period of time might even lead to losses because in the quest of hoping that the price will skyrocket then it suddenly starts dipping so it's really not ideal to accumulate for too long as no one can speculate or predict what it's future holds.
I might understand your point but I put it to you (Richbased) that you are completely wrong. Trading is a 50-50 game and/or gambling that is never advisable to anyone expect you are so good at it as a professional trader even as that it's still not advisable, you do not have a solid claim for disputing the fact that long term holding is not good.
Bitcoin as predicted has not reached it speculated price and as such you may be lucky enough to be among those who will be favoured with the uppity of the Bitcoin price as a result of long term holding. There is more chance of profiting with long-term holding that short term, infact a 99.99 chance of success for long term holding because after accumulating Bitcoin you will be prepared for but the upward movement of Bitcoin price and the dips at the same time. when you have a good portfolio or have accumulated enough bitcoin you cannot be affected by the price of Bitcoin at anytime because for sure Bitcoin can't go less than it has gone before and it has a guarantee that it will bounce back to a good price at any give time.
The area I highlighted makes sense to me about Bitcoin haven't reached the speculated ATH, I never knew that Bitcoin have a speculated ATH although even as Bitcoin has a speculated ATH all are still speculations as no one can really predict it's future but in that case I agree with you on buying and holdling bitcoins for a long interval of time but what if after the bull market then the price of bitcoins starts dipping? In such situation, what will happen to the bitcoins that you've hodl, like isn't the dip gonna affect the bitcoins? Well I don't know but if after the bull run and it's price dips and it doesn't affect the Bitcoin that have been bought and hodl then that sounds so interesting to me because the bitcoins can actually remain in the wallet till the next bull market without being affected by the fluctuations of price in the market.
But if peradventure bitcoins reaches it's speculated ATH does it mean that one can possibly stop buying and holdling or continue because I feel that if Bitcoin should reach ATH then investors may no longer be interested in buying and holdling since the price wouldn't go any further higher again.
