I have made a little thought experiment. I have thought about the BTC (early) investors who went 100% all-in - these heroes who put all capital into Bitcoin years ago when BTC was still in relatively early, immature stage and was not realized as the real asset.... AND who did not sold this investment before 2021 when BTC reached 1T$ (50k per BTC).
I divided them into groups by the year (the year they went all in) and gave every group (year) its colour and zodiac sign. At last I calculated the percentage how much of every group became USD millionaires and billionaires.
2009 RED OX - 100% (millionaires), 100% (billionaires)
2010 GREEN TIGER - 100%, 100%
2011 YELLOW RABBIT - 100%, 30%
2012 BLUE DRAGON - 100%, 10%
2013 BLACK SNAKE - 95%, 2%
2014 WHITE HORSE - 80%, 0%
2015 GREY GOAT - 90%, 1%
2016 BROWN MONKEY - 80%, 0%
2017 PURPLE ROOSTER - 30%, 0%
2018 ROSE DOG - 15%, 0%
2019 ORANGE PIG - 15%, 0%
2020 PEIGE RAT - 10%. 0%
For example the investor who put all his capital into Bitcoin in 2012 and did not sold a satoshi before 2021 has a title BLUE DRAGON in this system

Or may-be it is not suitable to name 2015 or even 2020 an early investor - then lets name all of them
super investors because their ROI was orders of magnitude higher than traditional (Gold,, S&P500) investors.
NB! The success rates are just rough estimates.
