Mine was having @raybrockman introduce my to the seemsilvergold group to get me pumped up on metals, and then buy a bunch of silver coins and bars. I think he spotted me on my intro post or one of my first ones, and I clung on pretty hard for a month or so. His advice also convinced me to buy my first ~300 Steem, which I sold shortly thereafter when I decided to earn it all instead. I just passed 5,000 a few weeks ago and it was as anticlimactic as it could be.
