I have the feeling that many forum users too have similar experience; do kindly share just maybe I can feel a little better knowing that I'm not a lone.
Pretty much the same as you. I made my first bitcoin wallet at blockchain.info in 2013 (yes, that was 10 years ago). I thought at that day, ain't no way there is stuff like that when I was really young at that day. When I checked the wallet few months ago, I actually surprised with how much Bitcoin I left there before. Sure, I felt the sense of regret about that. But, it doesn't matter anyway I have learned something about this and time to move on.
