My main assets are in the cold wallet (mainly Bitcoin, which does not interact, only deposits and withdrawals. Some of the Bitcoin in the cold wallet is used as holding positions and not moved, while others are only used for large period trading). Binance and OK are the main exchanges, and I rarely participate in on chain trading. Among them, Binance is used more, such as making profits and some short - and medium-term positions are only in Binance because liquidity is better. Long term trend trading is available in Binance and OK.
