提币白名单应写进交易计划
提币白名单能降低账户被盗后的资金转出风险，但交易者必须提前规划地址、等待期和应急流动性。
-
Withdrawal allowlists belong in a trading plan
Crypto withdrawal allowlists reduce account-compromise risk, but traders need to plan address setup, waiting periods and emergency liquidity before they need them.
-
资金费率不是背景噪音
永续合约交易者应把资金费率同时看作持仓成本和拥挤度信号，尤其是持仓跨过多个结算窗口时。
-
Funding rates are not background noise
Perpetual futures traders should treat funding as both a holding cost and a crowding signal, especially when a position is kept through multiple funding windows.
-
保证金档位会让仓位风险非线性放大
在期货和永续合约中，名义仓位变大可能进入更高维持保证金档位，因此杠杆风险并不是按直线增加。
-
Margin tiers make size nonlinear
In futures and perpetuals, larger notional size can push a position into higher maintenance-margin tiers, so leverage risk does not grow in a straight line.
-
大额转币前先做小额测试
转移较大加密资产余额之前，交易者应先用小额测试确认网络、地址、Memo或Tag、最低入账金额和确认路径。
-
Test transfers before moving size
Before sending a meaningful crypto balance, traders should verify the network, address, memo or tag, minimum deposit amount and confirmation path with a small test transfer.
-
换平台前先导出交易记录
在更换交易所、税务工具或关闭账户之前，加密交易者应先下载成交、转账和费用记录，避免成本基础和盈亏被算错。
-
Export records before changing platforms
Before moving accounts, changing tax tools or switching exchanges, crypto traders should download transaction history, fills and transfer records while access is still simple.
