They have 5 payment options, not only eth.
But i also want to know the amount that has been raised on the other options.
I want to see the proof of this total raised amount

Could you provide the address?
Would you be wiling to share your BTC address so we can monitor the progress?
I started to wonder why they have never answered questions like this

Only ETH is displayed on etherscan. The amount collected in other cryptocurrencies is displayed exclusively inside the site and is found in private.
