Description

Super Realistic, HD Simulation of Bitcoin Market Value. Play with the sliders to see what happens! There are 3 sliders that can be used: Stability: This controls the likelihood of whether the value will not change or if it will fall. It is a percentage. Positivity: This controls the likelihood of whether the value will increase. It is a percentage out of stability. So, if the value chosen is considered stable, another value will be chosen that will be considered positive or stable. Volatility: This determines how volatile the market is. Volatility is a random multiplier on the previously determined value change. This can cause either a crash or a boom. It works better the more stable/positive the market is. P.S. If you see part of the graph disappearing when the value gets too high, know that that is a limitation of the code.
