Snip.
Investments favoured the earlt ones, there might be many true bitcoin believers now but still, there is someone out there who bought bitcoins for fun when it was priced less than a dollar.

But the right ways is to invest on anything only if you are coninved that it will grow in future, but the problem is that not many of them ever heard anything about bitcoin that matters most than the preice and thought they wanted in it too.
Buying Bitcoin just because you see the price going up or following a trend (FOMO) is speculative, not an investment. It cannot be denied that those who profited the most from Bitcoin were those who got in first, but that was a small part of the total. Some of the people who lost the most were also those who got in first, but without faith in Bitcoin future growth.
In the past, there were many cases where people bought when the price was less than a dollar, and then forget about it. Another case also occurred where someone who was mining continuously managed to get several Bitcoin in a day, then threw away his hard disk in 2013 because he thought Bitcoin had no value.
They got in early, but didn't get rich because they didn't have the confidence to hold Bitcoin for 10 years. Those who truly profit are not those who enter early, but those who enter with confidence and are ready to hold on to Bitcoin even when the market is in turmoil.
