Do we mean by the end of 2020? If so, I think it's best to make predictions for the price in terms of BTC/satoshi's since the price is heavily dependent on Bitcoins price.
Current: 0.00001590 ~$0.12
2020: 0.0001000 ~$0.75
At today's prices that would put us at around $0.75. But, I'm sure Bitcoin will increase over the next year, right? We could easily see it over $1.00.
