What is most lacking in cryptocurrency trading is definitely not money or the underlying asset, but patience to wait until the opportunity for risk-free arbitrage appears before buying.

The best investment model is that every investor must always keep a certain amount of liquid funds in his account, ready for the best opportunity model to appear at any time - risk-free arbitrage.

Risk-free arbitrage is to use the price difference or unreasonable relationship in the market to achieve risk-free arbitrage income by making multiple transactions at the same time.

Simply put, it is to buy when it is incredibly cheap, or to trade when there is an opportunity to make money by selling immediately after buying. #BTC
