Coinapult charges no fees, pure spread.
Sure, but that is the fee to ach it to your bank account, just like the fee for a wire transfer with your service.
If someone wanted lock their BTC to a certain fiat price and keep that fiat with a third party than why not simply use an exchange?
BTC-e charges a 0.2% fee
bitstamp is 0.5% to 0.2%
kraken is 0.35% to 0.1%
So if I were to "lock" and "unlock" on btc right now I would pay
7.52 usd with coinapult
1.89 fee x2 + 2 dollar spread = 5.78 with bitstamp
0.74 x 2 fee + 0.14 dollar spread = 1.62 with btc-e
1.31 x 2 fee + 7.27 dollar spread = 9.89 with kraken (yours is better than kraken)
Am I missing something here ?
Hmmm... perhaps the locks and unlocks is just another way to spin what a normal exchange does and the real decision on which exchange to use has more to
deal with a trust issue , and how easy it is to get cash into the exchange, and the fees. I would certainly trust an exchange more with holding fiat if I knew who the owners were.... thus
I would trust coinapult and bitstamp above btc-e.
To clarify your first sentence, Coinapult doesn't handle wire transfers with retail customers. It's Bitcoin in and Bitcoin out, so there is no wire fee.
In response to your exchange fee analysis, you're right, Locks may not be the best deal for people that have already incurred the cost in time and effort to establish an exchange account. However, how many people have you tried to get interested in Bitcoin that gave up during the multi-step and often multi-week process of setting up an exchange account? Likely many.
With Coinapult, you can email new users bitcoin and they can immediately Lock. In less than 2 minutes, they can experience Bitcoin transactions without having to learn a completely new currency and without having to deal with Bitcoin's volatility. The less barriers new users perceive to using the blockchain, the faster adoption will take place.
One advantage veterans may find in wallets like Electrum that have the Locks plug-in enabled is convenience. Significant funds are held on exchanges because waiting 3-6 confirmations before market action can be taken can be too expensive, especially when there is high volume on the network. With Electrum + Locks, you receive a guaranteed price quote before you send funds. Don't forget that time is money
