I have just tried the LOCK feature,
Basically its their wallet, not yours. You set the amount you want to "LOCK" (max is $3k), then you're requested to send the equipvalent in BTC to their wallet either from your external wallet (any wallet) or your Coinapult wallet(basically you sold your coins LOL). The exchange rate is ofcourse the "hidden fee". ie Bitstamp currently at $593/btc, their rate is $584/btc. And i only tried less than 1 btc, i assume with larger fund, the rate is even worse.
I hate it when the Coinapult asshole talked like this feature is so innovative, while infact hes just taking the cut on every trade he does for you on the exchange.
Hi Seriouscoin, thanks for your feedback, hopefully we can explain why we think Locks is an innovation that goes beyond a normal exchange.
Anytime a user wants to use an exchange, they are taking ownership of fiat into a verified bank account. There are a few noteworthy disadvantages to this:
1. The non-trivial and time-consuming process of gathering and verifying documentation (days or weeks)
2. The lack of privacy
3. The necessity of having a bank account
#3 is perhaps the most striking. If over 50% of the world doesn't have a bank account, you are effectively cutting off 50% of the world from accessing Bitcoin as a payment network. One of Coinapult's primary motivations is bringing Bitcoin access to developing countries and economies, and requiring all of our customers to have bank accounts would not be conducive to our mission.
Our fee is not hidden, we have a spread of approximately 1-2% (closer to 1% when volatility is normal) any time someone Locks or unLocks. We are actually mid-preparing a new "Price Discovery" page for our site that will give more details into how we calculate an averaged BTC index price, as well as Coinapult's spread.
