can you explain more about the refund wall , because it sounds like a good idea. I liked this project since the start

Refund wall :
we're selling our token at the price of 0.00000100 btc = 100 sat , so the total amount is 150 btc
If we sold all the amount we will have 150 btc , after the ICO ends we will make a buy order of 75 btc ( 50 % of the sold token ) at the price of 0.00000115 btc = 115 sat
So if you bought our token and you want to get a refund you will get your money back with 15 % profit
