If you read my initial post then I was referring to people who "have been stacking BTC for one or nearly two cycles". These are the people who can understand dip well. Like I said, they are the one who have seen Bitcoin at 20k (few months ago) and they have also seen Bitcoin on 109k before witnessing current Bitcoin price of 84k.
For newcomers, there is only one way to move forward and that is go for Bitcoin accumulation without any wait. A newcomer will spend time in Bitcoin accumulation before he can figure out when it's dip or when to invest aggressively in bitcoin accumulation.
To see results, good and big ones, 5-10 years are needed to properly hodl and accumulate your BTC.
And no matter the price, it will be worth it, as long as the accumulation is steady.
I love how you put it which is the time recommended to see good result in your Bitcoin investment. The 5-10 years range is indeed enough to see significant growth in your Bitcoin investment if you maintain the accumulation religiously without making any attempt to sell as it is expected that you are buying with your discretionary income and also setting aside emergency funds. This is the basic ingredients of healthy Bitcoin portfolio management.
If you start investing in Bitcoin today as the price is around $83k, give the investment 5-10 years from today, the price of Bitcoin will definitely be far higher than the $83k which means that you will see big rise in your Bitcoin as your total invested capital will be multiplied by some factors greater than 1. In other words, irrespective of the amount you start investing in Bitcoin, so long as you can maintain the steady accumulation process there is bound to be significant increase in the price of Bitcoin as he continue to hold. This is the idea behind the long term recommendations.
However, don't make the mistakes of thinking that that range of years is the ideal time to sell because it is just a suggested duration you should be expecting to see significant profits in your Bitcoin. You can make holding Bitcoin a lifestyle, this way you will continue to hold irrespective of what the price will as your target will always be to own Bitcoin until a time will come when you would have retired from active service, then you could begin to figure out ways of enjoying part of your Bitcoin money and perhaps set aside some to be given to your children, loved ones and even charity.
