It isn't late too do anything until you have the fear of losing. But in case of Bitcoin you will at least not lose. You will make bigger profits in coming years as it would be world wide accepted electronic currency which is gaining acceptance at faster pace.
Correct. As long as you have money to buy bitcoin then get it. Although with the current price, it is so much expensive. But you have to look it at a long term. Get bitcoin now and try to save it in your wallet and go back after 1 year. It will probably give you nice profit but I don't how much because we all know that the price is quite unpredictable. But chances of bitcoin price going to the moon in the next year is quite high. So buy now and try to hold on it.
