This a quick update to the Pricefeed script I wrote in Node JS:
Crypto exchanges have the currencies paired with BTC and/or Tether (USDT). If USDT is at $1 USD, there wouldn't be a problem. However, USDT varies and should be taken into account, as it was underlined by @smooth. Currently USDT is trading around $0.99, thus USDT-based prices result in a 1% higher value. 1% isn't much, given the 5-10% regular fluctuations of any cryptocurrency. But, for the sake of precision, I have added the USDT/USD pair from Bittrex and Kraken into the price feed calculation to reflect the true STEEM/USD price.
- Application resilience with NodeJS restart on crash/exit.
- Automatic RPC switching.
- Averaged price from up to 5 major cryptocurrency exchanges: Binance, Bittrex, Huobi , Poloniex and UpBit.
- USDT/USD correction.
- If using the docker installation
I suggest you edit the config.json and set Binance and Huobi to
false, since their wallets are down and their prices a higher. Always keep an eye on the different exchanges and edit the config/restart accordingly.
