Bullshit BTC Price Projections, Now in Your CLI!

This is a re-implementation of Moon Math that runs locally as a CLI program. It's written in Go using the Bubble Tea library, and uses Coindesk to source price data.

Configuration

By default, the program will use Bitcoin along with various goals and bases of comparison. With the --config-file flag, however, one can specify a TOML file that overrides these defaults.

See this one for Ethereum for an example.

"Theory"

Given a pair of quotes taken at the start and end of some period,

 (t_s, p_s), (t_e, p_e) 

we can derive the total gain for that period, and its length in days.

 g = p_e / p_s 

 d = t_e - t_s 

Combining these, we can calculate the compounding daily periodic rate (CDPR).

 r = g^{1/d} 

We can use this rate to project the price p_f at some x days in the future.

 p_f = p_e r^x 

If we instead make p_f a target price, we can solve this equation for x, telling us how many days it will take to reach that target.

 x = {{log(p_f) - log(p_e)} \over log(r)} 

Future Improvements

• Add more default configurations for various assets.
• Allow projection by date, e.g. use the CDPR to calculate what the price would be on a particular date.
• Log errors to a file.
