I would use gdax preferably and buy Eth or BTC then you can use blocktrades from inside your wallet on steemit. If you want to go through bs and try to get a better price you can attempt to use bittrex or poloniex but I find blocktrades to be more than fair and very very fast.
RE: If litecoin (the first shitcoin in my opinion) can make it over $200 from $6 in 365 why can't steem?
