La Puissance des Intérêts Composés
En résumé : Les intérêts composés permettent de faire fructifier les gains générés précédemment, créant une courbe de croissance exponentielle.
Compound interest exponential growth occurs because your returns earn additional returns over successive compounding cycles. Combining initial principal with recurring monthly contributions accelerates portfolio compounding through dollar-cost averaging.
