Although the recent ETF speculation has brought Bitcoin to a new high this year, currently, the trading depth is at a historical low. As can be seen from our statistics these days, although the trading depth is increasing, But it is still insufficient and the market volatility will be greater. The reason for this situation is that on the one hand, the inflow of funds into the market is still insufficient, but the core is still the increasing number of long-term positions. More and more Bitcoins have become long-term positions. The reduction in the number of flows is actually the market turnover rate. If it becomes lower and loses enough chips, it means that there is no way to have a higher trading depth. Therefore, the near-term contract and options markets are particularly dangerous. Remember to have a stop loss on the contract and pay attention to the entry point for opening a position.
