How they are going to invest the coins of the HODLers,in order to make enough profits and be able to pay interest rates?
As loycev said, there won't be any bitcoin hodlers, there will be only hodlers of promises of payments.
For the model, I can think of a pretty easy scheme of investing, use the bitcoins to push bch price up, dump their coins at a profit, as for the "investors" they can be paid interest from the money new investor deposit in the ponzi scheme. Oh, did I use the word Ponzi, how awful from me! Of course, this ain't a ponzi scheme, I mean Roger Ver had absolutely nothing to do with BitClub, he said so himself!!
Many newbies could indeed fall for this "offer", but beware, they usually have only some Satoshi and may be disappointed if they won't see (unrealisticly) big growth in their wallet.
And many will fall, a lot fo them won't have even those satoshi at first, they will be tricked into buying directly from the wallet, and they will see some shiny numbers there, thinking they are both holding bitcoin and earning interest when in reality there is nothing. Half of those newbies will never think of installing their own wallet and withdrawing coins to it, just as there are thousands thinking they hold bitcoin in their Revolut account, so there will be thousands falling for this scheme.
