Yes I agree. I came to many of these conclusions myself. Bitconnect works because it is in a financial environment that is always going up rather than a fiat money environment that is always going down because the banks keep printing money. 
I also invested $10O dollars back in May and as you say it has not missed a single payment.
I became concerned when I saw these pop videos because the message is a good one - if the people at BitConnect are genuine that is. If they are not then the consequences would be devastating.
If you saw at the bottom of this blog I suggested that we might be looking at the first crypto bank made in a rising currency market. If this is true then BitConnect is nothing but a revolution. 
Time will tell.
Thanks for commenting and good luck : )
