For a long time, the vast majority of people believed that BTC, as the market leader, drove all altcoins to rise and fall in sync. In fact, when BTC, ETH, and SOL have been in play for a while, it becomes evident that SOL is actually leading the ups and downs of BTC. Whenever SOL starts to decline, BTC inevitably follows closely behind. Therefore, these three coins should not be traded simultaneously in contracts; after the halving of BTC, the rhythm of the latter half of the bull market is not in sync. If all three coins are traded simultaneously, one of them will inevitably be trapped during a market reversal. There are several strategies for the contracts of these three coins:

1. Trade only BTC;

2. Trade only SOL;

3. Trade BTC and SOL together; when SOL rises to a certain high point, prepare to short BTC;

4. Trade BTC and ETH together, which are basically synchronized. ETH is slightly lagging behind. Whenever BTC reaches a high point and starts to consolidate, ETH will always make up for the increase, and then it will pull back after the increase.
