Are you serious

Take a real look at the order book : in the bids side, there are 150,250 bids at 1 satoshi, 24,937 at 2 satoshis, 20,000 at 3 satoshis... and so on : these are "fake" bids.
You can't compare these ridiculous more than 200,000 unreal bids (compared to the 218,416 total at this time) bids with those aroud the market price (600,000 sats) : be serious.
Between 4 satoshis and 600,000 satoshis, the reality is they are only 18,000 bids !!! How many bids beetween 600,000 and 500,000 satoshis (for example) ? Very few !

Look at the order book graph, for example with a 25% price range and you will see how the market is really imbalance and can collapse at any time.

For my part, my XZC are sold now.

I was the french translator of RISE [ANN].

How does it change the serious ZCoin security problem?

I am not weired and I'm not a newbie like you.

The big mining centralisation of ZCoin is a big issue for his security, no (51% attack) ?
How the community can manage this ?
How the dev can do something ?

If the security of the coin (his blockchain, then the mining) is not guaranty, ZCoin value is zero.
Very sorry to tell this :-(.

yes, you are right Once The price can hit 0.03btc then They will feel regretful with the selling action. I still hold my zcoins until MTP algo and Masternode will be released in next months.

sometimes it does get stuck, i found just closing and re-opening, or the post above to re-index should get it working

That sounds good, I'll follow you.
IF XZC can trade on poloniex, I think 70$ is easy !

Wise decision, it will pay off big time.
