You can see it yourself on coinmarketcap.com, the charts are the same all the time. Is there a link between them ?
The name Bitconnect itself means connecting to Bitcoin. So yes there is a connection in between both coins. Most of the time their charts are similar to each other. Whenever the price of Bitcoin rises, we can see a spark in the price of Bitconnect too. Bitconnect has been making the profit in their lending platform out of this strategy only. They invest in Bitcoin and just hold the money. The price of Bitcoin rises which makes a profit to them and that is how they pay the interests for their lending program. This is the reason why the BCC lending is still running.
