The next Bitcoin Halving will decrease the Block reward by half. So a Block will generate only 6,25 BTC which means that the supply will decrease and the demand will still be increasing. If Bitcoin At that time is still successful its price should go up a lot
i also think that in the next halving the price of bitcoin will boast as the demand of bitcoin will increase and the supply will decrease, i am hopping that at that time the rice of bitcoin will be trading above 4000 USD level. if the proce of bitcoin will continue its trend of increasing its price.
