Interesting. I've also been in traditional markets as well since I had my first real job. Got into crypto on this years down slide around June-July after a friend told me about ethereum. It opened up a whole new world of investing. I to thought I was late for bitcoin. I bought some for balance but concentrated on altcoins more. Now I wish I bought more bitcoin. Like you said, never too late.
I have high hopes for 2018 as well. Bitcoin going mainstream will bring a lot of attention to the whole crypto space. We are still in the beginning stages of this whole blockchain revolution. I'm very glad to be here as well.
Good luck and good fortune my friend!
