It takes only an Expert to discern a Ponzi scheme from one that isn't on the blockchain network. This is mainly because most platforms here requires just little information from you and this is displayed by the fact that most exchanges allow traders to execute trades on their platform haven submitted only their Email address, the fact that most of these exchanges doesn't even necessitate KYC is a supporting evidence to that statement.
A Ponzi scheme is simply a scam site and that is exactly what I would be reviewing on this review today. This platform is known as the BitConnect Client. It's already evident in the name of this wallet that it was primarily established to store, send and recieve the BitConnect coin. The wallet has its applications available on both desktop and mobile devices, a factor that could have caused mass adoption of it and the fact that the wallet allowed staking of this BitConnect coin on their platform could have caused it.
The reason for calling the wallet a Ponzi scheme is because of the fact that the wallet just stopped operations without even notifying traders that use the platform, thereby leaving so many traders with great losses of their BitConnect coin. The wallet just stopped and their website is presently not loading at all. I guess traders out there should be careful with it.
