@haejin, I'm a 100% positive on your thoughts on this one. Besides ethereum I found 5 others to keep an eye on:
- Ox (ZRX) gives me an "up-trend" comparing to BTC
- Gas (GAS) a little weaker, but still worth looking at
- Request Network (REQ) .......not sure, but just keep an eye on it
- Qtum (QTUM) still looks strong
- Lisk (LSK)
..........and if they go down with BTC they're still a good investment for the coming year to hold
