How much is a 500 peso bill worth?

Excuse me, could you please clarify the value of a 500 peso bill? I'm a bit confused about its worth in comparison to other currencies or denominations. Is it still considered a widely accepted form of payment? Additionally, could you elaborate on any potential fluctuations in its value over time, especially in relation to the cryptocurrency market? It would be greatly appreciated if you could provide some context and insight into this matter.
