Talking about BTC: Bitcoin's recent trend is volatile, with fluctuations of 3,000 points. Contract players are probably also covered in wounds! There are many gamblers around me who have been liquidated! It doesn't matter how many times you win, as long as you are always there, there will always be a time when you will lose everything! This is why many exchanges are developing contract transactions, and some even open secret channels to do futures contracts for compliance, probably because the profits are too lucrative! If you hold spot, this drop of 68,000 is just a tentative adjustment, and there is a high probability that it will continue to break through. I personally think that the target of BTC this year is likely to reach 100,000. It is better not to do contracts if you hold BTC, and never forget the painful lessons of 3.12.
