It is really hard to predict the value of Bitcoin in that year and that is because Bitcoin is a currency so it is hard to know what is going to happen in the future.
But nobody will ever know what will happen also with the value of Bitcoin so that is bad, but they have to know that it can takes a long time until it will reach a high value.
Well even price at the end of the year is hard to predict accurately because it's obvious that no one really knows what will happen.
In pointing out the price, we can't say what will be the price in the future but if we point to the usage, it will truly grow in percentage since doing bitcoin transaction is definitely the smoothest transaction we can experienced by sending and receiving the money. Most users that don't care for the price will hug bitcoin because of that factor.
