I will update this initial post with the answers in bold people were kind enough to give so others can quickly get them and also know what is still unanswered and we need help on.I'd like to know where I should be trading bitcoins. I did some reading. People here suggested poloniex and bittrex. But, this contradicts
https://en.bitcoin.it/wiki/Comparison_of_real-time_trading_exchanges, which lists neither!!! Needless to say, I'm confused.
So let me ask three specific questions:
Q1: If I submit a BTC/USD limit order, and it doesn't get filled before I cancel it, who will charge me the least?
CURRENT BEST ANSWER = all exchanges = 0% (unfilled market maker order)Q2: If I submit a BTC/USD limit order, and it DOES get filled before I cancel it, who will charge me the least?
CURRENT BEST ANSWER = bitmex = -0.0250% (filled market maker order), but bitmex is not allowed for usaQ3: Who allows shorting BTC?
ANSWER: bitmex and bitfinexAlso, who has the smallest bid ask spread and/or most liquidity? I see way different prices on some of the exchanges listed at
https://bitcoinwisdom.com/. Bitfinex seems to have the most volume, so they should have the tightest spread and biggest level 2 order book, correct? bitcoin.it implies that there is a taker and maker fee of 0.2% across the board. That is messed up to me, but about what I would expect in this somewhat corrupt world. I know at coinbase one can trade but the sell and buy prices are ~$10 USD different, or about 0.15% fee either way. Isn't there a sensible exchange in the USA with $10/trade rates like an old-fashion US stock broker? Do any exchanges allow trading on margin?
EDITED ANSWER: bitfinex and bitmex.I used bitcoin.it to learn about a few exchanges, but the bid ask spread on them was ~$50 USD, which is way too wide to be going in and out, something I'd prefer to be able to do so long as it doesn't break the bank.
Thanks.
