My investment position is slowly shifting from on-chain to off-chain. @okxchinese Although the shark fin has been removed, there are still dual currency win options available for structured products, which means options. For those who like shark fins, you can go on-chain to play with sofa, but I don't know if there are any protocols for dual currency win. I actually really like on-chain, and if the same business is being done by a new project, you can also get tokens, which adds extra bubbles that make on-chain returns easily surpass off-chain. Unfortunately, there are indeed too many issues with DeFi protocols at the moment. The returns from dual currency win are much higher than the recent DeFi mining on-chain, and there is no smart contract risk. The only risk is getting stuck with BTC after this bull market crashes, but holding BTC in the long term isn't considered a risk. If you bought BTC for high interest and are worried, just hang on and wait for a high sell; it's like doing a swing trade. If the long-term trend changes, just treat it as holding coins. This return is also closely related to the price. For example, on the 6th, buying low at 102,000 can lock in a 20% APR. After the price rises, if you want to buy at 20% on the 10th, you can only buy low at 106,000, which makes it easier to trigger the option strike price. High sell = sell call, low buy = sell put. Of course, even if you don't understand options, you can still play; just remember to only play with BTC.
