I guess that a lot of people feel that they missed the Bitcoin train and just jump at every new promising opportunity they get, hoping that this time they will be right to get in from the start... not a bad thing to do, though you should still carefully choose your battles. Zcash does look very promising, but jumping all in without even getting all the details first can be a problem and I'm getting the feeling that many people actually do that. I won't be surprised in seeing a lot of people tomorrow that will just rent enormous hashrate right from the start of the mining from NiceHash and then figure out the hard way about the initial very low rewards.
