Some people are saying BTC will be $1 million per coin in the future. But when that will happen I really don't know. Its all about mass adaptation of BTC and other cryptocurrencies. The fact that now there are stringent regulations on cryptocurrencies have made many investors back down from crytocurrencies (including BTC) . In my opinion this is why the current market is kind of stagnant in terms of BTC price. Mass adoption, more conducive regulations by governments will astronomically increase the price of BTC,  but what's that exact price? I really don't know!
