It's unfortunate that the tokens aren't valued in BTC rather than USD so that investors can benefit from rises in BTC price.
Right, but the profit does shift with price changes as it is counted in terms of USD, so there is some degree of rise with any BTC/ETH/LTC jumps in price.
It's only to a lesser degree (for now) while the initial token price exceeds that of the profit divided by 100 million.
