I think they'll keep growing for months/years unless they get caught by the FBI or someone. They can last a lot longer with crypto, have the standard income and the increase in token value, expect the owners are holding a lot of their tokens.
Steem is basically a ponzi scheme aswell though, it has no income. Even if it did display ads they wouldn't make anywhere near as much as is given out in upvotes.
yes their is a big risk of the SEC going after Bitconnect and shuting down the website.
Difference with steemit , simple users don't take risk, only investors buying steem do, we have all the data available to take decison, and what is promised (distribution of curation and author rewards) can be verify in open source code. If steemit website is down with your keys you have still access to your funds.
SEC is just as likely to shut down Bitcoin as it is Bitconnect.
No sir Bitcoin can't be shut down, this is the principle of dencentralization but i agree Bitconnect can be.
