Investing is when you buy something and hope that its price will rise after several years. This was not the case with Bitcoin in the early days, as the probability of failure was high and Bitcoin had no long term value.
Only a few people knew the potential of Bitcoin in 2011, so I don't blame him for his losses. Maybe I would have also sold mine immediately when the price increased. Those who kept their coins to date should be celebrated because it took lots of courage and patience to achieve that.
But it's not yet too late. Many people still don't know the potential of Bitcoin. I registered on a forum where they were discussing investment, and nobody knew much about Bitcoin. When I began to narrate my experience with Bitcoin and how the price has increased over the years, they called me a scammer. I never told them to invest but most of them believe that Bitcoin is a scam. So we are still at the early stage and there is still time to keep accumulating.
