I heard Ethereum guys have announced to dump their BTC collection resulting in a price drop. Any idea regarding this ?
Don't think the price drop was due to that, though it might have spooked a few. BTC needs a fresh impetus to maintain the prices with new coins coming in each day. The challenge from the 2.0 coins might hurt it as big money is flowing in them.
I dont think any of the alts pose any threat to BTC.
