I might start investing on bitcoin soon. I cheacked through the link and it's like, "Bitcoin for dummies", in my opinion. I like it. Thank you for the link!
As others have said, it is definitely not too late. The only problem I see with your thread is that you have placed it in Trading Discussion, and it is much better to invest in bitcoin than to trade it.
Trading is buying and selling trying to guess whether the price will go up or down and it is a much touted system but one that over 95% of people lose money on.
Investing, on the other hand, is based on a thorough knowledge of the asset you are buying and basing your purchase on the fact that its characteristics are such that it will have a prosperous long-term future.
It is better to go for this second option, as you seem to point out, it is much safer and with less risk.
