I would have bought way more Bitcoin at the very beginning. I remember first coming across Bitcoin when it was under 100 USD but I did not think of it much then... I considered it a fad but I did not really understand how it worked or that it would be so important in the future.

And I would have registered on this forum back in 2012 instead of lurking around occasionally and registering in 2017 finally. I missed out on some fun times with the community.
