In 2010 I stumbled on a Bitcoin article on the net and after thinking over it and rereading the article repeatedly for over two months, I went to an exchange and bought 10 BTC for $10. I followed the developments and articles in the internet for a few months and then completely forgot about my $10 worth of BTC. I had lost interest and patience. I moved on to other things.
Then one day in mid 2014, I saw an advert in front of a building at a popular bus stop saying EXCHANGE YOUR BTC FOR CASH. I was elated. I rushed home and dug out the details of my BTC purchase and my wallet Address. I rushed back to the exchange office and asked them to take a look at my wallet and do anything necessary to change my 10 BTC to my local currency. The young man who attended to me could clearly see I lacked much knowledge about the transaction.
To cut a long story short, he transferred my 10 BTC to his own wallet and gave me $100 Dollars worth in local currency. I was ecstatic. After all I bought the 10 BTC for just $10. I left the office fast thinking I had made a huge profit.
A few months later while browsing the net, I came across the current price of BTC to be $415 and I nearly had a heart attack. I researched more to make sure my eyes were not deceiving me and sure enough, the 10BTC I exchanged happily for $100 out of ignorance would have easily fetched me $41,500 that year 2014. And if I had held it till today, I would have smiled to my bank with $670,000 and retired a millionaire to maybe the Caribbean Islands.
This memory always brings tears to my eyes whenever I remember the foolishness of my being a stranger to the internet in those years. Learn from it.
