# o copie a propriului environment. Bot-ul si-a incarcat .env-ul la pornire, deci
# environment-ul mostenit contine parola veche, iar load_dotenv() (fara override)
# nu suprascrie o variabila deja existenta -> se trimitea parola veche la BT si
# nu mai pleca push-ul 2FA. Nu folosim load_dotenv(override=True) pentru ca
# bot-ul transmite intentionat prin environment variabile de rulare
# (TELEGRAM_MESSAGE_ID, TELEGRAM_CHAT_ID, SEND_AS_ZIP, BALANCES_ONLY).
