What makes ETH special?
ETH is special because its innovative new technology is supported by a critical mass of developers, finance, and industry.
Dash has no such technology, nor the required ecosystem of coders and financial resources. They are selling snake oil, not real solutions.
Can it over take bitcoin in terms of adoption I read a lot of rumors that it's going to take over bitcoin how is that possible,all I read about Ethereum is just being pump by some fews that has the resources to make any coins pumped out,
