have you guys ever shorted solana?

i use binance and ive seen the “Cross” option, which is next to “Spot”. ik it means i can borrow money (ofc giving some collateral) to sell the token so if it goes down in a certain period of time (without getting liquidated), i can buy it back at a cheaper price making profit from it, have you guys tried it?

maybe is there any safer and decentralized way to do this so i pay less fees than doing it on binance?

another question, have you guys used borrow money (its the same but inverted) to buy and x2 or x3 your gains? i think is called leverage in stock terms aight?
