The Peruvian nuevos soles or sol, SI (symbol) or PEN (code), has been Peru's official currency since the Central Reserve Bank of Peru introduced it in July 1991. It replaced the Peruvian inti because of hyperinflation and a terrible economic status in the early '90s. Since it was put into effect, Peru managed to improve its economic status, and the currency maintained stable exchange rates.
Because many online casino sites accept the currency, Peruvian players of live casinos can fund their online casino accounts using the Peruvian nuevos soles. This makes their playing sessions at online casinos convenient, considering they can avoid the hassle of converting their local currency.
