The statement it is never too late to get started is meant for beginners who just got the opportunity of knowing the importance of investing in Bitcoin for holding and for those who out of fear refused to take advantage of the price of Bitcoin to invest when the price was not very high like it is now but for someone who is new and is willing to invest in Bitcoin the motivation in this thread and the achievement of some strong holders should encourage them to start buying Bitcoin daily, weekly or monthly depending on the income flow or the person because no matter when you realize the importance of buying and holding Bitcoin, holding it for 10 to 20 years I'll definitely give you hope in the future no matter the amount you have invested.
Looking at the highlighted words, I strongly disagree with it because the purpose of accumulating Bitcoin consistently is to have a very huge stash of bitcoin that can impact your financial status in the future when bitcoin has gone up to a million dollar or more in the future, but in my own opinion, you can't just invest any amount and be expecting something huge.
If you are referring to the statement you bolded that was made by @mvdheuvel1983 you are definitely not getting what he is saying correctly because his point of saying those things was for even more longer term than others has planned to hold so actually the reason i said you shouldn't have disagree is that the purpose you said of accumulating huge Bitcoin is the same way he presented his idea about it because the 10 or 20 years he mentioned could give you a lot of bitcoin when you will see the summary of your Bitcoin but however @mvdheuvel1983 is only not correct by saying no matter the amount someone use now they would have alot of Bitcoin because is not certain for such person with just very small amounts they were even struggling to invest.
