The 10 year plan ended in February 2020 and Bitcoin was $10k at that time. The prediction was off by wide margin but still good. I never imagined in 2011 that Bitcoin would to that high,and now we're at $62,000 and still going.
I currently have some crypto (BTC, ETH, LTC, etc) but nothing compares to what I'd have got from the Investment plan, or even remotely close. I lost an opportunity to become a Bitcoin billionaire!
This can be a story for everyone who started early, if i were to hold the coins i had which will be over thousand Bitcoin, i will be setting my life for good, but i sold my profit and had a great time in the mean time traveled the world and had a great time and even though i do hold majority of the coins as savings, i too lost the opportunity to make a much bigger profit like you claim .
