Bulgaria · BGN
What happened to your money?
The same story, told 3 ways: in BGN, prices only rise. Measured in Bitcoin satoshis, the picture inverts. Each chart says what it is — observed data or a labeled model.
Plain arithmetic · 2021 → today
10% of one month's salary, converted once in 2021 = 233.5k sats — worth ~$180 today
1.7× in USD terms. Backward-looking arithmetic, not advice — the next 5 years are not the last 5.
01 · Prices in Bulgaria keep one direction
Observed · World Bank CPI
The official consumer price index rose 52% over the last decade — the BGN buys steadily less of the same basket.
02 · One BGN, measured in sats
Observed · FX snapshots × BTC closes
2014: 1 BGN bought 199.6k sats. Today: 763. Log scale — the fall is the story.
03 · The same paycheck, in sats
Modelled · today’s salary held constant, BTC-only
Today's average net salary (1.41M sats/month) replayed across BTC's history. The model holds the salary constant — only Bitcoin moves — so this is the pure Bitcoin side of the story.
