    "提现规则是什么？": "老板您好，现在提现方法有手动提现和自动提现两种方式。,自动提现规则：,1、每天一次自动提现，开启自动提现后，每日上午6点到8点期间，每日余额超过500元才会自动提现。,2、钱包余额低于500元无法自动提现时，商户可选择去APP或PC端手动提现。,手动提现规则：手动提现设置最低额度，钱包余额超过50元，才可以手动提现。低于50元的钱包余额后续商家闭店后可以将此金额提现到银行卡/支付宝中。,注：默认要求提现人完成实名认证，提现收款银行卡与提现人同名，非同名不能绑卡。,温馨提示：平台提现到账时间为即时到账，一般会在10min左右到达您银行卡，如果您提现没有立即到账，建议您后续关注，预计会在1～3天到账平台提现到账时间为即时到账。"
