Why this amount of BTC or ETH specifically? Can we deposit less?

Despite of our strategy works well for any amount we aim to attract a limited number of users with higher deposits.
We also have some expenses per user to be covered with our part of profit. So the higher deposit is - the more profit can be earned.

How do you make sure that the interested party pays to you half of the profit? For example, they can give you an API key without a withdrawal option and keep the entire profit for themselves.

You are absolutely right there, you have pinpointed our weak point. We have zero control on user's account. We do not ask for withdrawal access so we can not take our part of the profit by ourselves. But instead we are focused to provide the best service, therefore user will be interested to continue using our service and send our part of profit in a timely manner.

So risk-free with a guarantee? how do you guarantee?
whether you use escrow service, and if something goes wrong with my deposit, then you will pay me back with your funds?

Risk free for you as we guarantee you a sure profit. Your balance can not be decreased otherwise you will be compensated.
We use 15 days control period. For example you have 10 BTC at the 1st day and after 15 days of using the service your balance is say 9.8 BTC - so we will pay you 0.2 BTC. We have special reserve fund for this purpose. But for 8 month of using and testing our strategy there was not even one 15 days period that end up with a loss.
That is why we are so sure about our service and guarantee you a sure profit while having a reserve fund locked and loaded in a case of emergency.
