Repeat after me - "We're in it for the long haul" - because one day everyone will be using blockchain technology for public transactions and billions of people will need Bitcoin, Ethereum, EOS, Tezos or whatever to transaction trillions of dollars of business, contracts, property rights and information transfers every single day.
While private entities may try to annex use of blockchain just like cryptopgraphy, the Internet and other tech - it's out there now. The Pandora's box of blockchains is open now (thanks Satoshi, whoever you are) and ain't nothing going to put it back again.
So sit back and enjoy the ride, diversify your portfolio so you have a few thousand (or whatever you can afford) in the key blockchains, and keep your eye out for promising new-comers like EOS, Tezos etc. or whatever blockchain based apps you feel like supporting such as distributed exchanges, DAOs, prediction markets or hey, even spam blocking. Then be patient.
Remember how long it was since the first very public Bitcoin "bubble"? BTC at $1200 USD and then crash all the way back to $200. OMG, it's all over. Bitcoin is done, it's history! Completely forgetting that only months before BTC was in double digits. Then fast forward a few years and were at BTC just shy of $3000 and ETH at over $400 up from $1 just 18 months ago. Even when they crash now there are still billions, yes billion, invested in them and BTC and ETH based ICOs.
All I can say is once again "We're in it for the long haul because you ain't seen nothing yet!"
