I read some posts of my fellow Filipinos selling SBD to BTC (cashing out from Steemit) recently and my reaction is -- OMG (SAYANG!) LOL
I would never "sell" my SBD to BTC due to blockchain FEE. See below comparisons:

We could "sell" Steem/SBD to LTC/DOGE via BlockTrades and Coinpot first (BTC to Coins.ph PHP withdrawals) or ETH/DASH /LTC/DOGE for Poloniex/Bittrex or BitShares (invest) or ETH/LTC for Coinbase users (USD withdrawals) to save some FEES. Dogecoin has the LOWEST FEE.

I have an account with Bittrex and Poloniex but I prefer @BlockTrades (quick and simple) and Coinpot to convert (DOGE/LTC/BTC/BCH/DASH) for free and consolidate my earnings from FAUCETS and Steemit when CASHing OUT (to save some fees again when transferring BTC to Coins.ph).
Will publish a 5,000 words article (exaggerating. LOL!) soon. Stay tuned!
