现货下单前先看盘口深度，不要等滑点出现才复盘
单看最新成交价不够。盘口深度能帮助交易者判断流动性、滑点，以及突破是否有真实挂单支持。
-
Check order-book depth before a spot crypto trade, not after slippage hits
A price quote is not enough. Order-book depth helps traders judge liquidity, slippage and whether a breakout is supported by real resting orders.
-
模拟交易适合练流程，不适合证明策略稳赢
Binance、OKX和Bybit都提供模拟或测试环境。它们适合熟悉下单流程和爆仓机制，但模拟盈利不能等同于实盘证明。
-
Use demo trading to test the workflow, not to prove a strategy
Binance, OKX and Bybit all describe demo or test environments. They are useful for learning order flow and liquidation mechanics, but simulated profit is not live-market proof.
-
Use crypto price alerts as a risk tool, not a trading signal
Coinbase, Binance and Kraken all support alert workflows, but a useful alert plan should separate watchlist movement, trade triggers and stop-loss discipline.
-
合约网格机器人是区间工具，不是被动收益机器
Binance和OKX都把合约网格描述为区间内自动下单工具。核心风险在于：杠杆和趋势突破可能把小额网格利润变成较大的方向性亏损。
-
A futures grid bot is a range tool, not a passive income machine
Binance and OKX describe futures grid bots as automated range-trading tools. The key risk is that leverage and trend breaks can turn small-grid profits into large directional losses.

Set the exit order before you increase leverage

Maker 与 Taker 费用会改变加密交易的真实成本
适合高频或短线交易者的平台，不只是界面顺手。Maker/Taker 费用、价差和等级规则都会改变最终成交成本。
-
Maker and taker fees change the real cost of crypto trading
The best exchange for an active trader is not only the one with the cleanest app. Maker and taker fees, spreads and tier rules change the final execution cost.
