You may not blame yourself that much, because at some certain point, when we are not clear about a particular thing, we tend to withdraw from it instead of going into it and we ended up being disappointed, as we know before now, that many already have been scammed as a result of related deals, which makes it more difficult to easily trust anything new.

But to your own personal interest as of now, i will say this that if you're still interested in bitcoin mining its never too late to at least start from somewhere, it is better late than never, because mining bitcoin is still profitable and you can set up a rig even now to mine it, we still have a numbers of years before we could mined the entire bitcoin completely.
