yeah, I've been a huge BTC lover since 2013 - but it is having serious and fundamental issues - particularly withe Blocksize debate and as a result, the ridiculously high transaction fees. I mean, what - 5 or more dollars now? That's ridiculous. That totally shuts out any smaller shops (coffee, corner stores, or even clothing or smaller electronic stores from wanting to accept them.)
It's really too bad, b/c the tech behind it is great, but it's the damn humans on the traditionalist side who are effing things up. They don't want to evolve with the times. This is already really hurting BTC as most crypto-currency start ups are now using ETH.
(just happy I traded some of my BTC for ETH last summer - now my ETH is the driving force of my crypto-currency portfolio.) :-)
