The instawallet wallet API is might interesting, because a) they don't charge for wallet to wallet transfers and b) they don't charge for API use.
So with functionality to a) create wallet b) transfer c) interrogate balance, all of it for free, my questions is:
* why should i bother with a bitcoind + dealing with the wrapper interface for my programming language of choice*
I can think of various pros and cons:
PROS:
- free
- has all the functionality needed
- means I don't need to set up and secure my own bitcoind
CONS:
- could go down anytime
- no guarantee the wallets won't disappear tomorrow (inside theft)
While the cons are pretty bad, it sounds good enough to run a proof of concept type project.
What am I missing?
