正常来说应该盘前低流动性拉盘，才有人会去打预售。Wlfi第一轮1.5b的市值打1.5亿刀，都打了几个月，即便trump发币后，也有2天的时候可以打。最后还是孙哥直接塞了1500万刀才瞬间结束的。这pump 4b的市值打6亿刀....我真不知道不拉盘怎么塞满，所有有硬顶的打新，都是一群人观望，等进度到40%-50%才开始加速打钱。但是这个有盘前合约，理论可以套保打预售。不过，我应该不会这么玩，或者玩太大仓位，以前被那种锁仓的坑怕了。最后，如果是前几天的大盘，如果盘前合约不拉，那就可以直接做裸空了。低流动性都不拉盘合约pvp，难道开现货一堆人打进去了，拉盘送钱吗？结论：我认为应该要拉盘前，才会有人打预售。如果盘前都不拉，那么开盘更没人接盘，应该做空。谨慎套保打预售，防止搞锁仓等幺蛾子。 ...
