Bitcoin is a kind of currency but not for massive adoption. Bitcoin is like Gold, it's a lazy placement, not a currency. To be honest, I am sure that eBitcoin will one day overtake Bitcoin. eBitcoin fixes all Bitcoin issues... also the massive adoption, scalable and environment issue. Many here know about the potential of eBitcoin and are agree with that. A currency should be used by all the people, BTC with congestions cannot (And I am a BTC lover !!)
eBitcoin (eBTC) is :

—> Bitcoin code source on Ethereum Blockchain
—> Environment Friendly
—> Unforkable
—> All tokens are premined and in circulation (no miners issues and really deflationist)
—> Highly scalable with the Ethereum network
—> Faster (much more faster than BTC : 10-15sec tx for eBTC and 10-30 min for BTC)
—> Cheaper transaction fee
—> Possibility to send 255 payments within 1 transaction (1 fee)
—> Fit for mass adoption
—> Less congestion than BTC network
—> Sharding and plasma in the future
—> A smart Ecosystem with many crypto partners working together as a global team
