Ethereum has been outperforming Bitcoin recently and I thought this would mean Bitcoin’s dominance would be declining, but CoinMarketCap and TradingView show that it has not changed very significantly.
Do not let those altcoins (like ethereum) to deceive you, you will see them pump but later you will notice that bitcoin performed better in long term. Ethereum is yet to get to all-time high.
They always saying that since they are trying to hype people to buy Ethereum. Lots of them try to create a good hype for that coin since maybe they think about that altcoin would start once there's a bullish movement happening on Ethereum.
But for many times they failed and their expectation didn't meet that's why there's lots of discussion about this and some other people deceive that Ethereum is doing good compare on Bitcoin. For me I'd rather focus on Bitcoin since I see a good growth although ETH is doing good but for me Bitcoin movement is doing more fine and profitable especially for those people who choose to HODL it for long time.
