there are many factors that make it possible to believe that bitconnect isnt a ponzi
bitconnect has its own blockchain, the price of bitconnect token is going to the moon
those are just 2 things that make it easy to believe that it is possible for them to pay out a small interest of 1% daily
if the core devs just keep selling token it is possible to pay out 1% a day and again look at the volatility and the rise of 90% of altcoins over the past year makes it even more believeable that it is possible
and as far as a ponzi- every business out there uses money from sales to pay off merchants thats just how business works
if you run a business and you sell something you probably make some kind of deal with a wholeseller that you pay him back after you sold your product- thats just common practice for most businesses - that means everything would be a ponzi
