Thanks for that, that opened straight away.

Looking through that at a high level it shows exactly what I expected.

Bitcoin falls from $230 to $56 and in turn the equity in the company (it's shareholder value) falls from $2.1m to $800k. That is with only $2.5m of total deposits to start with vs almost identical capital. Obviously this scales up if the deposits are larger and there's no way this business will be a success with only $2.5m of deposits.

It's really simple, if you claim to make money from BTC rising value then you (or your customers) must lose if it goes down. The risk profile is symmetric, unless you add assymetry via external option purchases, which are not mentioned (and no-one could write the volumes anyway).

This business is not a bank, it's a bet.

I suggest Neo can attempt to disprove this by showing what the profitability looks like with a 5% decline every month for a year and with substantial deposits. The reason is must be done like this is usually it's hard to make perhaps 1-3% on gross interest margin, so you need deposits that exceed your capital by a large factor to make profits once costs are accounted for. Most banks have leverage ratios (assets/capital) of 20-30 for that reason.
