It is hard living in the land of what ifs and should haves. If I kicked myself for everything I missed I would be bruised and probably dead. I'm learning not to be that too smart conservative skeptic and just be diversified and take chances.
I must tell you though I'm so thankful that I found steemit last year and that is when I started learning about crypto currencies. Here I've been into computers since 1980 and sure I've done well off my software but I never invested into anything but land, silver and gold. But now I'm playing catch up at 56 and a little more diversified.
