i saw, that on this exchange, https://yobit.net/en/addcoin/, we could let add quora within 2 days for 0.1 btc.

Has anybody experience with them? Is it worth the investment? And if yes, is someone here who wants to share with me the costs?

I always use the universal. But as i had the error i switched to the win, but with the same error.

Good to know.

Are you using the universal wallet or the native one?

i think i have the problem. i had a timesync software called dimension4 installed. as i activated it yesterday, a few hours later, i got the same problem again. It seems that the timesync of the wallet, that happens if a new block is received and the timesync of the dimension4 software are not compatible together and under special conditions the wallet crashes with the above error.

the new clean install is now running fine for ober 12h. I think its ok now.

but it is nevertheless strange. My installation works since 0.22.0 came out fine and then yesterday stops working...

All the issues that I used to have, disappeared when I synced after downloading the DATA folder and not from the start.

i make now a clean install with seed recover and full new download of the blockchain....

Are you running the latest Qora wallet release? The mapDB errors were solved long ago I think

i now added the timezone in settings.json. perhaps that helps.

but if i look at http://qora.co.in/?

I would love to see QORA  LogIn on Drupal, (Joomla, WordPress) by QORA Token, something similar to https://wordpress.org/plugins/nxtauth/

Integration with Drupal user point (https://www.drupal.org/project/userpoints) would be also nice. QORA or QORA assets as payment (rewards on blockchain!) system inside popular CMS platform will be huge. I know I will use that.
I can add 1,000,000 QORA to these goal.

I created a feature list that can be used for future development & crowdfunding. Feel free to comment/edit:

1)  Market place (where users can sell or bid for items)
2)  Reddit style platform
3)  Chat (supporting creation of channels) embedded into wallet with default #Qora channel
4)  Qora forum on Dec.Web
5)  Game services (eg gamble apps with bounties)
6)  Payment modules for famous website builders - e.g. Joomla, Drupal
7)  Forum creation on Dec.Web with frontend/backend
8 )  Website creation with CMS capabilities with frontend/backend
9)  Conversion scripts from Joomla/Drupal into Qora web for existing web sites
10) 100% wallet GUI transformation into web wallet
11) Price ticker into wallet & android/IOS widget & firefox/chrome ticker plugin
12) Charts inside Asset Exchange
13) Pie charts inside Voting feature
14) Android/IOS wallet
15) Paper wallet
16) QR support
17) Web wallet for those not wanting to install Qora locally, eg blockchain.info wallet type with 2 factor authentication
18) Gift card service - supporting Amazon, Starbucks cards etc
19) Gold/Silver exchange into AE, that helps peg price or exchange Qora for gold bars (needs merchant)
20) Ad support (needs discussion)

and that's the reason to never trust bter again. do not use their price index anywhere or better, do not use them at all.

In our case, we were depositing Qora.

BTer was holding each successive deposit longer and longer, starting at a few days, then weeks, now months before crediting the deposit.

Luckily, as the deposits took longer, we were reducing the amounts.

With the last deposit, they immediately transferred the funds to their forging wallet, then began claiming the wallet didn't work, when we can all see it is working.

This was 3+ months ago. We have not received a reply from support in nearly 1 month, but the replies were pointless anyway as they all say the same thing no matter what question you ask.


... or many variations of the above. They've never addressed a single question we've asked.

100m up through 12 sats is for sale on CCEDK.

Anyone here who wants to sell its big Qora stake? I want to buy Qora for 1 BTC at 8 sats. This would be 12,500,000 Qora.
Please pm me if someone is interested. I'll call an escrow.

maybe I can understand why bter pending withdraw(disadvantage of circulating assets), but not realize why dont transfer deposit to account(few week ago make unsuccessful test with 100qora)
