The highest level will be achieved by bitcoin if we follow the cycle known as Halving Day, which rewards per block will decrease every 4 years or every 210,000 blocks. This reduction will have an impact on the overall supply of bitcoin so that bitcoin will potentially be more expensive because it allows demand to exceed the supply in the market. The first Halving Day we went through was in 2012 where 25 bitcoins per 10 minutes were made by bitcoin miners. And the second Halving Day in 2016 produced 12.5 bitcoin per 10 minutes and will again be reduced to 6.25 bitcoin per 10 minutes in 2020. Therefore, if we assume demand is fixed or increased the new supply circulating in the market will not be able to compensate existing demand so that prices can become up.
