Apparently, most persons feel this way and so, they keep wishing they had known earlier. Funny enough, there are a lot of other persons who knew but failed to dive in. Why? They never thought for one second that it could worth anything or would have any break of day about it. As such, they sadly failed to invest and still stood in the shades watching bitcoin rise. Even now, I can tell you that, majority of the world's populace are still on the sidelines watching bitcoin rise and still don't own the least sat.
It's the way it is @OP, there would always be regrets becusaes, a lot of persons aren't investors and as such, don't have the insight. What makes you think you would have been any different @OP!
