I use Coinpot. It is FREE to transfer 0.0005 BTC or more (within 48 hours process). I hope it remains FREE. 😊
I use SBD to buy Steem (select market) then sell STEEM to DOGE/LTC. Altcoin conversion to BTC at Coinpot is also FREE. Will publish a blog about my first Steemit cash out as soon as I receive BTC via Coins.ph (for fiat). 👍
