No late, Bitcoin is still hot for you high profits. You can still invest in btc or other altcoin, which is not too late
profits are not a guarantee. the price could very well crash following this price spike we've been seeing. not that I hope that's what'll happen, but entirely possible. but yes, I agree it's never too late to invest. who among you here heard bitcoin back in 2009 and 2010? I was one of the people who is very skeptical about it and I really regret it. 
I missed the best opportunity for a lifetime.
At that time, bitcoin is only a reward from faucets. I think they give 1 btc per click and if you are the one who believein bitcoin at that time may be you are now a millionare because you have a percentage in the total bitcoin available now, unfortunately, I also dont believe to it so I have regrets =( I missed the best opportunity for a lifetime.
