You can't see order book on coinbase and quickly trade in and out.
None of the other sites allow you to buy / sell with ACH.
Second Market is open to members only; not everyone. You have to be a member that is well funded to trade with them.
CampBX and Coinmkt are exchanges. We are not. Think NYSE and E-Trade. We are the E-Trade.
On a related note, I hear horror stories on /r/bitcoin all the time about bank accounts being shut down over supposed BTC activity. Does your service have a solution or guidance for this?
There are many banks in the US with very different rules so it is difficult to give a general answer. Have you heard of these stories from customers when buying and selling from coinbase?
In another industry, this probably wouldn't be a red flag; it would just be standard marketing practice or startup posturing. But when you're dealing with money services, you don't get to be dishonest, unprofessional, or unprepared.
You've tripped quite a few red flags with your comments on HN today. I definitely won't be doing business with your website.
CoinSetter is kind of a hybrid broker / exchange and they offer fee rebates on coins purchased via ACH through coinbase.
I guess my point is why would I want to trade with you, a new and unproven company, that out of the gate is making a dubious claim of being the "first" of something of which there are already many. This is Bitcoin if you are making dubious claims on the small stuff how can we make the leap of faith that this isn't just scam company n+1
We are more like E-Trade in that your order will execute on an exchange and the price is whatever is available at the moment. We don't frontrun your order. We plan to make money on trading fees.
This is directly from coinbase's terms of service :
"3.1. Transactions with Coinbase. When buying or selling bitcoin through the Exchange Service, you are buying from, or selling to, Coinbase directly. Coinbase does not act as an intermediary or marketplace between other buyers and sellers of bitcoin. The Exchange Service is subject to the Coinbase "Conversion Rate." "Conversion Rate" means the liquidity adjusted price of a given bitcoin amount in terms of local currency as quoted on the Coinbase Site."
