As far as using electricity, it won't be long before it reaches the limit and can't be mined any longer, hence no more use of electicity

Yes, I agree. This exact thing happened to me when I tried to buy at $20 a year ago, right before it shot up to $40 and they cancelled my transaction also. Can anyone tell me where a decent exchange might be for the US right now. If I feel like selling my BTC I'd like to be able to do so.

Yes, reason??

Ya, rough man sorry. Same thing happened to me but they got back with me pretty quick. I think I was on another link though.

Yup, they did the same thing to me! The price of BTC jumped the day after I ordered and all of a sudden my trans was cancelled. They said my email wasn't from a trusted source??

Hey super noob, just purchased BTC for the first time and seemed to go through really well except my coins haven't showed up in my wallet yet. I put my wallet address into the Coinapult address bar and it said funds sent and gave transaction ID. but wallet still shows a balance of 0 after 4 hours. I only downloaded the wallet a few days ago. I'm just wondering how long I should wait before I need to worry that something went wrong or if there is another step I need to perform to get the coins to my wallet? Any help would be appreciated, thanks!
