In the year 2010,my best friend introduce me to cryptocurrency and he advice me to invest in bitcoin. I felt bitcoin was another ponzi scheme created by scammers to scam innocent people. Today my friend is a multi Millionaire. If only I had listened to his advice,I would have become a millionaire by now.
That was a sad story to hear but I don't think it was actually your fault because back then no one believe that bitcoin will be expensive and high and most people was seeing it as a scam then and even if I was in your shoes then I believe I would've make same decision or choice you made because I will see it as a scam too and then investment was somehow not popular. But even if you invested in bitcoin then, just like what one of the commenter said I don't think you would've hold it till now just like most people couldn't hold theirs.
Regardless of the fact that OP didn't give much explanation about his post this is just a mere cook up story because it lacks proper information to convince others that he was persuaded to invest in Bitcoin as far back as 2010, people who owned Bitcoin didn't even have it much value and the recognition was very low because many people don't know about Bitcoin because cryptocurrency were in their early stage of their invention so they didn't believe that Bitcoin will become this vast and the awareness was just very few people however, i tell people not to always depend on people's opinions before you can take a decision yourself.
You're right I think back then bitcoin has not become this popular in the market most people may not even know about bitcoin back then in 2010 because the value is still very low, at that stage most people will be very careful to invest in bitcoin because they don't know about the potential in the future, but with the way op sounded in his post looks like his friend knows that bitcoin has a good potential in the future. back then in 2010 no one can guarantee you about the future of bitcoin, those Investor's who get profited from bitcoin investment are just people who took the risk to invest in bitcoin without even paying attention to any risk, however most of those earlier investors didn't hold on to it for Long term investment most of them sold it in the process why most people were patient enough to hold on to it till when the price skyrocket.
