You are an early adopter! :D
If STEEM and it's blockchain don't make it out alive, then 99% of the rest of them are gone too. Almost all serve no purpose as yet - at least we have something right now, and SMT on the horizon.
The Steemhunt tokens are just the start, I suspect we'll see much more airdrops like this in the future. I ain't worried, just feeling the pinch :)
Absolutely. All the Graphene chains are going to be rife with tokens of every description indented for thousands of purposes. The crucial difference between them (EOS, Steem, and Bitshares) and Ethereum is the fact that the latter will not pass muster before transitioning to Proof-of-Stake about which there is a great deal of disagreement as to how to go about it. The Dan&Stan chains will scale first and that will be a large advantage.
