Binance exchange allow us to buy and sell levereged ETF token
for example
Btcup/usdt or Btcdown/usdt with leverge x2 - x4
Ethup/usdt or Ethdown/usdt
When you buy the a token you own the token in your wallet and you pay daily fees 0.01% for every day holding the token
for example you buy Btcdown/usdt knowing from the chart price might go down
so if the price of bitcoin goes down your token value go up in price,when you sell you pay fees for selling
from what i understand no loans to repay or risking liquidations
