       Funny thing is, at the current feeding price, there is basically no place to buy such a cheap BTS. Witnesses actually think that the feeding price is no problem.
       For example, I bought 500,000 BTS in DEX last night. Each BTS cost me 0.404 RMB (2.1% of recharge rate is included). But the feed price is 0.395. Please tell me where the 0.395 BTS is available. Or which witness is willing to sell it to me at this price?

I can sell you BTS for 6.2 cents like gdex-witness feeds if you want :)

Time: UTC 14th May 15:08

BTS price in CNY should be about 0.4124*1.009 = 0.416CNY







Warning: verbaltech2, fox, zapata42-witness, blckchnd, delegate-1.lafona feed a price 2.3%+ lower than reasonable level.

sorry, gdex-witness will check and update USD price feeding, however that's not the excuse for you to not feed well. :)

Was only joking to point out double standards. Already explained what the issue was on a different thread due to fake Vols combined with zb API being down.

Feed looks stable now... Will adjust as needed

in my view, generally speaking, below are some principles to judge whether a witness feed price well enough.

1. feed price should reflect the price at which the conversion can be done between BTS and the pegged fiat.

2. feed price should be updated frequently enough to reflect the real market price.

3. for smartcoin with enough market depth in trading pair with BTS in DEX, such as bitCNY, feed price should not conflict with the modified DEX price, which means the DEX price plus the smartcoin premium/discount.

So we would get margin calls on DEX (with 1.01) which would be more expensiv than BTS at regular price on CEX ?

Other stable coins like bitEUR or bitRuble should also get a MCR of 1.6 and MSSR of 1.02.
@bitcrab: Can you initiate a vote for this parameter to other FIAT stable coins?

I think the user who use the bitEUR or bitRuble should think something more, because of these bitasset didn't have the Fiat gateways in DEX and didn't have the Fiat Trading pair in CEX.

How the user can detemine the quality of feed price? which price is the real fiat pirce?

But the funny things is the user of bitUSD seemed  these didn't need to care about.

@binggo: For bitEUR price feed we can take a bitUSD price feed + EUR/USD exchange rate.

This is wrong.

EUR-USDT-BTC-BTS-BTC-USDT-EUR, there have some trading loss and charge, you take 1 EUR in maybe only 0.96 EUR out, the 0.04 EUR must count in the feed price.

If you want EUR chang to USD, you need to count the exchange loss and the charge.

It's not simple, and the feed price publisher must know these, if the feed price publisher didn't know these, please kill the stablecoin.

yes, maybe, when all the price is market price and bitCNY has a 1%+ premium.

The prices offered by zbbtsbp were not updated for several hours and had deviated significantly from the actual price
