This got me cracked up, I don't think the price of bitcoin can grow to as high as $1 million in just 1 year, that will make me a bloody billionaire, lol.
Though this can only happen in our dreams in 2020, I can say that we should be seeing a rate of $100,000 per btc during the fourth quarter of 2020 which might still dip with over 50% loss when everyone begins to take out profit. Based on my speculations, I think it might take up to 5 years before we can get to the rate of $1 million, then bitcoin would be mainstream.
