I would like to send some BTC from Kraken to Bitfinex but the transaction fees are high, ~30$. Is there a better way to transfer money like: buying LTC, ETH or some altcoin and send it?

- BTC withdraw Kraken fee: 0.00100 BTC
- Bitfinex deposit fee (less than $1000): 0.0005 BTC

If I change BTC to some altcoin, the maker fee is: 0.16% from BTC.
