Question: Is there any reason to take BitcoinCash, BitcoinGold, BitcoinDiamond, BitcoinPrivate, etc etc seriously?
Ok so umm I will not say that you shouldn't take these things seriously because I do not like to make predictions with certainty, I do think that airdrops are not free money, airdrops come with a rather significant price attached to the price is loss of privacy.
In order to take advantage of it you have to use keys that already had a balance before the fork and and those keys perhaps if you been doing your operational security properly those keys let you control several different addresses, but what happens if you straight cash out on one of these forks?
Well most users are going to do this in a very naive way, which is aggregating all of the UTXO in a single transaction after splitting and moving it out, well you just Associated all of those addresses and of course not just for the new fork but for the original fork you kept it on, so you associated with the addresses in Bitcoin that you had your Bitcoin on because of the transaction you did for BitcoinCash (for example) and trust me intelligence agencies analytics firms and anybody else who has the desire to do data analytics is watching and they're going to know exactly what you have where you have it and which addresses belong to you.
And if any one of those addresses associated with exchange or merchant that does KYC (know your customer) or has a shipping address for, your name attached to one of those addresses, now all of those addresses have your identity attached to them, that's a heavy price to pay to collect an airdrop.
I haven't collected any airdrops let me put it that way and I probably won't.. (:
