It is too late to buy Bitcoin. All exchanges of the world are closed and no one wants to sell any more. Sorry, but you will never be able to get Bitcoin...
It is not too late to buy bitcoin. As you mentioned that it is too late to buy bitcoin. It is too early to buy bitcoin in these days because if we buy bitcoin now so later we will enjoy the future so we need to withdraw our bitcoin near 2020 if we buy right now because in 2020 the price of bitcoin will reach to $8000 USD which is quite possible for bitcoin in these days.
