Been comparing a few options for sending money home and the rates are all over the place depending on the day. Between the big names (Chipper Cash, Flutterwave-based apps, PalmPay, Wise) — which one has actually given you the most consistent, best rate over time, not just a one-time promo rate? Also curious if anyone's tracked how much the rate shifts around month-end vs mid-month. Trying to time transfers better instead of just sending whenever I remember.
