Ok, it is not what you are thinking.
Bitcoin is not a Get rich quick scheme, but the UK series "How To Get Rich Quick - Season 1 episode 3 includes some footage of a rich entrepreneur, Dave Fishwick, creator of Bank of Dave, discussing Crypto currencies as one investment option to become rich.
Luckily for us, the Bitcoin price at the time, generated a small profit when that episode was shot and he even commented that the profit he made then, were the equivalent of 3 years of interest in a local Bank.
I made 800%+ profit on my initial investment over a period of 4 years. (200% per year) - Go watch the series, it is full of good tips for the budding entrepreneur out there.

Edit - I wonder how many people will only reply to the Thread title and not on the content of the actual topic now.
The bitcoin market as at the time the UK series was shot was so profiting and at that period most of those who invested in bitcoin earlier before 2017 made huge profits on the investment and most of them became rich within a very short period of time, but those who bought during the hype of 2017 lost a lot of money from 2018. Bitcoin investment is a very risky investment so at that it better you invest in bitcoin when the price is low and wait for it price to rise then sell again.
