I find it quite amazing btc holds 55% dominance over other crypto currencies and is at $1500+.
I remember not so long ago it was 86% and a far lower price.
Madness.
Bitcoin dominance has been lowered due to a few reasons like the transactions taking so much time and also due to blocksize debate, people are searching for other alternatives and going towards other stable currencies like ethereum.
This is the year of altcoins like ethereum and monero.
Stable? Ethereum's hardly that, once those coins stop being pumped into ridiculous price ranges and people start rebuying bitcoin we'll see price on bitcoin rise up again. That can't happen without SOME resolution to the scaling debate, though.
