You were certainly not crazy and I envy the number of SMART tokens you bought at THAT price (3.4 cents) and WHERE the price went in the bull run ($3)! I don't know if you sold or not but that was some massive run. I think you sold some if I remember correctly.
I came here again because I am writing about how I purchased my first SMART tokens recently and I needed to link this post as my first exposure to Smart Cash. Or may be this is not the one I am looking for. The price was around $0.40 at that time. I'll look for that one.
I didn't sell, but my son did. I'm holding SMART as a long-term play, but I do think it needs a lot more adoption and volume to ever get stable. There's a lot of inflation and a lot of coins out there, so who knows what will happen. I do like that they are serious about building a payment network outside of the current system and they want to help those who need it most.
