$DOT You must cheer Ethereum more than btc to rise.
Eth can drive the price of dot and every alt coin better than BTC.
Why.
2. Dominance of alt is leading by eth
3. Same community dev. Gavin wood was fired from ethereum founder, then came to dot, so it may relate inside significantly.
4. BTC just expand the market cap only, but it not guarantee the new low of alt coin. It just allows the alt coin can make new high, but the price action depends on their utilities, partnerships, and developers.
