Price of Bitcoin is increasing at a very fast rate  but i dont think it is possible that 1 BTC will cost $1million .No doubt its demand is increasing and people are taking interest in it but for 1BTC to reach $1million it has to be declared as the world's currency and the only currency for financial transactions .$1million is a dream figure for all the Bitcoin holders and if 1BTC will reach $1million then it will be like a dream come true for all them as they will get very huge profits.
