I am currently all in alt cins and believe same like you that they will rise, but there can be a direct relation of hard fork to alt coins and they can also crash as btc seems to be crashing at that time, but this is crypto, we have to take higher risk to get higher benefits, this is the game which we are playing and the higher risk is the cost for that game which we have to take.
RE: When BTC hardforks, what is the coin to benefit the most?
