It was when I have known BTC for the longest time but doubted buying it during the early years when its value was just 1000usd. I thought of it as another Ponzi scheme since I have trust issues before. I was too surprised when it reached a good value last 2017. I never thought that Bitcoin could go this far. However, I believe that it isn't late for me to invest in Bitcoin again so as much as possible, I'm accumulating more of it yearly because I don't want to have the same regrets again.
