I believe this is the key that might prevent the big farms from having a large advantage right at the beginning. By design, they should not have that much of an advantage with their current hardware - ASICs for Bitcoin, GPUs for Ethereum, ??? for other coins. They have more funds to set up the hardware than the rest of us, but, if the announcement of the parameters are delayed until just before the genesis, they might not have the time set up thousands of rigs needed to overpower the “amateur” with a couple of PCs. Making a mistake in choosing the hardware could be very costly when talking about thousands of PCs
