it seems like after buying bitcoin the price is guaranteed to go down in the long-run. it starts off at 15k and in my save, it is now as low as $800

@ferguslesley the bitcoin price is driven by the daily random number generator. It looks like the increase/decrease is capped at +/- 20%, but the decrease can exceed that at very high prices. Anyway, you can toggle back/forward to restart the day and reset the RNG to get a higher bitcoin price.
