Comparing MNX to Bitconnect just reveals that you don't know the project at all, and how the interests are generated.

1) they come from the miners, not from some trading bots that nobody ever saw
2) the funds are not locked away, you can do whatever you want with them
3) the interests are only here to reward people for their participation in the price stability
4) there is no referral system at all
5) Minexcoin has never promised any returns in $$ or BTC, just more minexcoins

There is literally nothing in common whatsoever.
