Choose the right compliant exchange, and keep your deposit and withdrawal security—this is the bottom line for survival.

Build foundational financial understanding and learn to read macro cycles—this is the foundation for making profits.
Those who ignore risk will ultimately be cleared out to zero by the market, without exception.
Second, learn to read cycles—this is the crypto world’s underlying code: a bull-bear cycle every four years is the most certain rule in the crypto universe. Just like the cycle of the seasons—spring brings growth, summer brings long expansion, autumn brings harvest, and winter brings storage.
Trading in line with the trend is always the highest level of trading wisdom.
In a bear market, plan your positions; in a bull market, lock in gains. Don’t go all-in against the trend, and don’t trade recklessly.
