For those who feel that the bottom of the market has temporarily passed, they can consider selling put options on SOL and XRP @ deributofual; Sell the put option on SOL's 110 at the end of May for a premium of 5.7% (annualized 40%); Sell XRP with a bearish price of 1.8 at the end of May, with a premium of 6.6% (annualized 50%). Anyway, if it really falls below that point, buying some SOL at 110 and buying some XRP at 1.8 can also be considered as buying at a low level. These small coins' royalties can all be used in U.
