远征1-21存档文件，一步到位

Dear Valued User,

At the request of global users, a PayPal top-up channel has now been added.
Current exchange rate: 1 USD = 300 OB.

Notes:
Due to policy reasons, the transaction fees and withdrawal fees associated with PayPal are excessively high for us (we incur approximately 39.7% in fees for every $100 withdrawn). Furthermore, as a player team, we cannot bear the financial losses resulting from fund recoveries caused by illegal top-ups from certain high-risk accounts.
For the above reasons, the exchange rate of 1:300 OB has been set.

尊敬的用户您好：
应全球性用户的要求，现已增加PayPal积分充值渠道
目前兑换比例：1usd=300ob

注：
因为政策原因PayPal包含交易手续费与提现手续费对于我们过高（我们每一百美元提现一次手续费约等于39.7%），同时也因为我们是玩家团队，所以我们无法承担某些黑户非法充值所带来的资金追回所产生的资金差。
故此设定为1:300ob兑换比例
