To do so, open the wallet menu, and click "Deposit" to receive an address (Bitcoin's equivalent to an account) that you can send your bitcoins to for them to appear in your UpTweet wallet. If you have more bitcoins than you can find goods on the UpTweet marketplace to buy with them, you can withdraw your bitcoins and use them in the rest of the Bitcoin economy too. There is a wide variety of goods and services available for sale for bitcoin, including digital goods, clothing and accessories, professional services and more in thousands of stores around the world; there are even ways to convert your bitcoins into prepaid debit cards, gift cards or even money in your bank account or cash.
Looks like you will be operating a 'wallet' type service. How will depositors be reassured that you won't just claim you got hacked and run off with all the coins? Will you have any security or account auditing by a third party? Will there be any insurance on these deposits?
Thank you for these excellent questions.
It is not our intention to operate a wallet service. We are adding language to our website to make clear that UpTweet is not responsible for any Bitcoin losses to a user account.
We take security very seriously. Changes are being made to UpTweet such that users are only able to withdraw to their own previously set address. When the withdrawal address is changed they will receive email notice and withdrawals will be suspended for 24hrs, allowing them to respond to any unauthorized changes of the address.
