Personally, I've always regretted why I didnt discover crypto currencies earlier, even if not in 2009 when the whole journey started, atleast of I have discovered this by 2011 or 2012 when bitcoin was still very cheap, probably I would be very rich by now, but maybe I wouldn't have believed it if I've seen it then, but all good am here now and hoping for the best.
Crypto currencies has been the best investment for me, I mean am not rich yet but my life have changed alot after I started investing in crypto currencies, and am so happy for what the future holds, I pity all that still think crypto is not real form of investment, when they will realize how late they are, we must have gone far.
