Because the "FIRST USE" of blockchain (or encrypted ledger technology) was a $$$MONEY$$$ (Bitcoin) it was able to "catch the interest" of the average person in our dog eat dog striving to survive bankster driven sociopathic soul sucking of a black hole culture designed to control the slaves as hey are given their bread and circus.

Na, Bitcoin, Lightcoin, BitcoinCash, Dash, Zcoin, Monero, Ripple,,,, these are all "THE MOST LAME USE CASE OF CRYPTO"....... period. (I'm just saying)

ETH
EOS
WAVES
IOTA
DragonChain
BAR

All of those above are "Development Platforms", some are called "Virtual Machines",,,, they allow one to program a "DECENTRALIZED AUTONOMOUS ORGANIZATION" that can say make having politicians a useless thing (which it obviously already is).

Then there are individual industries, like KODAK and VeChain which tracks products cradle to grave guaranteeing Authenticity and Temp. records for food products to guarantee safety.

And there is other stuff like OneGram which is backed by physical Gold, and COBINHOOD (COB) that offers an Exchange with NO FEES.....

If someone thinks this REVOLUTION is going to be short lived they are not aware of what is going on,, there will be "loosers", a lot of "money coins" might be the bigger loosers as you will see FOOD coins PHOTO coins (KODAK) CAR coins MOTORCYCLE coins, BOAT coins HOME coins HOTEL coins ,,,, there will be individual or groups of coin in EVERY area of the economy and the ones that will take over are the ones that offer the best deal to the consumer (for example COBINHOOD).

Oh ya,,, and don't forget STEEM !!!!! This is the new paradigm baby !!!!

Good luck investing out there. Be smart, don't play with what you can't afford to loose. But this IS the OPPORTUNITY that comes along once in a lifetime.
