Time Cave (http://www.timecave.com), an email-scheduling service that has operated since 2000, started accepting Bitcoin earlier this year. (Unfortunately, though we have thousands of subscribers, not one person has yet paid with Bitcoin.)

The block-chain-based nLockTime solution is more elegant, but you can also use various websites (like ours at timecave.com, which is free for simple use and recently started accepting bitcoins for an enhanced service level) that delay emails into the future.  Time Cave has operated reliably for about 13 years and currently lets you schedule emails through 2025.

Of course, you'll probably want to (1) encrypt your wallet and (2) use more than one service like this, just in case.

I'd like to announce a relatively small but established web-based service (which has been operating for about 13 years and has about 30,000 users) that has just started accepting Bitcoin. It's called Time Cave (http://timecave.com) and allows people to schedule email messages in the (far-ish) future.

The site is not particularly Bitcoin-related -- but as I've followed Bitcoin's development over the years, I've noticed that many users of Bitcoin think long-term, and I could imagine the site might be useful in a small way for some of you.  For example, you could use it to store an encrypted ECDSA private key and pass it on to a family member in 10 years automatically, unless you cancel the message.  Or you could do something similar to enact a kind of "forced savings," or just a long-term backup. Of course, you might use it for messages entirely unrelated to Bitcoin too.

The service is free for up to two messages per day. It accepts contributions, and it has an "upgraded" service level that allows unlimited messages (within reason) and a variety of other features, like recurring message.  Our subscription fee has been $12/year.  We've priced Bitcoin payments proportionally for now; that is, at the moment, we'll use the general prevailing exchange rate for all subscription payments over 0.1 BTC, rounding the length of the subscription in subscribers' favor if there's any ambiguity (sharp price changes or what not).  So, for example, at $55-$60/BTC or so, you'd get a six-month subscription for 0.1 BTC.

Time Cave has a long and interesting history. Please don't judge the site on its graphics! The front-end hasn't been updated since 2000, so it's very much a "retro" service.  No Web 2.0, no heavy use of JavaScript, no connection to various irritating social-media sites. No web ads or privacy-invading features. But the back-end is rock solid and has delivered millions of messages, many over long periods of time.  Obviously, Outlook and other clients can do similar things today, but Time Cave doesn't rely on any particular client, and it's not dependent on GMail or some other large service.

I'd love any comments you've got in addition to questions about the site's Bitcoin acceptance.

PS -- Please don't make timecave.com a target of attacks!    We don't run a Bitcoin node on that server, and we don't store private keys on any online systems. The server has a bulk set of addresses, not unlike those that can be generated by bitaddress.org, and it assigns them to individual accounts to track payments.  It's all very rudimentary now, but it seems like a simple way for a service-based website to accept Bitcoin and price services accordingly; it took something like 20 lines of code to add the feature from scratch.

Thanks.  Yeah, that's roughly what I had in mind. It could perhaps just serve as a reminder about the money and a pointer to various encrypted backups.  Or perhaps it stores either the password for an encrypted copy of a private key (stored elsewhere) or the encrypted key (with the password stored elsewhere).


Annoyingly, the website doesn't support editing -- you have to remove the message and reenter it -- but it's something we'll add eventually.  (As you can probably tell, we've been slow to update the interface!)  We have an iPhone app that allows direct editing without deletion/re-entry.


Thanks!

Hi there - Could I get whitelisted per the information I left in the following post?

Thanks!

I'd like to announce in the main forum a relatively small web-based service (which has been operating for about 13 years and has about 30,000 users) that has just started accepting Bitcoin. It's called Time Cave (http://timecave.com) and allows people to schedule email messages in the (far-ish) future.

The site is not particularly Bitcoin-related -- but as I've followed Bitcoin's development over the years, I've noticed that many users of Bitcoin think long-term, and I could imagine the site might be useful in a small way for some of you.  For example, you could use it to store an encrypted ECDSA private key and pass it on to a family member in 5 years automatically, unless you cancel the message.  Or you could do something similar to enact a kind of "forced savings," or just a long-term key backup. Of course, you might use it for messages entirely unrelated to Bitcoin too.

The service is free. It accepts contributions, and it has an "upgraded" service level that allows unlimited messages (within reason) and a variety of other features, like recurring message.  Our subscription fee has been $12.  We've priced Bitcoin payments proportionally for now; that is, at the moment, we'll use the general prevailing exchange rate for all subscription payments over 0.1 BTC, rounding the length of the subscription in subscribers' favor if there's any ambiguity (sharp price changes or what not).

Could I get approved to announce it in the general forum (and perhaps some guidance on which particular "Service" forum would be the best place to announce it)?  I'd be happy to write a more specific message there that introduces the service a little more thoroughly. Thanks!
