The allocation of funds is based on a per basecurrency basis. Allocating your BTC does not affect you ETH market funds allocation configuration. If you operate on multiple base currencies there's 100% to divide over each selected market per base currency. So working with 3 basecurrencies will grant you the option to allocate 3 x 100%.
