Many of us regret after we see the potential of bitcoin, most of us regret not become the early adopter, but it is not too late to invest now, there is still big chance that you can earn big profit, so dont hesitate to invest in bitcoin now, especially now the price is a bit low
If you look at the grande scheme of things, you could still consider people that invest now 'early adopters'.
It's not like Bitcoin usage is that wide-spread, there is still ample room for massive growth.
