Bitcoin will definitely increase but it won't reach 35k, we have to see a very weak market condition, and for the increase I think it will range at 7k.
Predictions will be there and these made people more greedy but as per experts we can assume that for year 2019 BTC price will reach around 8k. There might be increase or decrease but we cannot guarantee on the price we can just predict based on some research on the market.
