I hate that I only got interested in bitcoin recently. If I'd been able to buy some bitcoins when it was still dirt cheap, I'd look like a smart guy right now. I was more into stocks and mutual funds before, but now that bitcoin seems to be gaining more popularity, it's high time for me to buy more before I get left behind once again.
That's not a big issue. Being into bitcoin now too doesn't looks to be so late. If you work hard with bitcoin possibly you will earn high.
Bitcoin will stay for very long time. It is still in the very early development stage. So it is not too late to join.
