I wish I were an Early investor on bitcoins as in the early stages it was worth less than a dollar and now the current price of bitcoins have come upto $ 7516 USD which is a good price. Last year the bitcoins price has hit the highest hit record of $ 19700 USD which has changed many early investors lives, even if some one just invested last year at the beginning of the year also the price was less than $ 1000 USD still he could be a millionaire or billionaire out of investing in bitcoins. There is no other gateway to earning huge profits other than bitcoins, still there is good potential for the bitcoins to increase its price so I would recommend investing in bitcoins than real estate.
