There is a huge mistake in the first link: Bitconnect trading bot IS NOT trading bitconnect coins but BTC with USD and USD with other currencies... as is said on their "
Volatility Software" announcement page. However there is still no proof of the existence of this bot.
Here is an extract of the page I just linked:
The software will auto calculate the lending interest and is based on volatility of BTC against USD and the volatility of USD against major world currencies. The higher the volatility, the more uncertainty is attached to the expected return on your investment. You can also calculate expected return on an asset by Bitconnect interest calculator, uses previous 7 and 30 days average to calculate return on your investment.
