The first returns response like:

https://bitcoinfees.earn.com/api/v1/fees/recommended
{"fastestFee":102,"halfHourFee":102,"hourFee":88}

price was based on fastestFee value.

like:
 null != e.fastestFee ? this.buyBitCloutFields.bitcoinTransactionFeeRateSatoshisPerKB = 3 * e.fastestFee * 1e3

New is like:

https://api.blockchain.info/mempool/fees
{"limits":{"min":93,"max":403},"regular":186,"priority":269}

price is based on priority value ^

like:
 null !=  e.priority ? this.buyBitCloutFields.bitcoinTransactionFeeRateSatoshisPerKB = 1.5 * e.priority * 1e3
