Lending AltCoins in exchange

[amaral1977]

Lending AltCoins like LiteCoin or Eth in exchages for margin trading gets a rather small interest.
Do you think this rather small passive income is worth the risk of keeping this coins in exchanges Like bitfinex or poloniex?

but bitfinex support too lending use fiat money USD
in exchanger support lending only bitfinex and poloniex
