Bitcoin and ethereum are investors' favorite because of their large liquidity and active trading in the market. For some time to come, I think it is difficult for investors to shift their portfolios of the two coins unless there is a coin that is able to exceed the market cap value of the two coins. For now, some of my favorite coins besides Bitcoin and Ethereum are coins that are in the top 30
I agree with you! My favorite coins since the time I joined the cryptocurrency market have been always BTC and ETH. Those two biggest coins have high volume trading and large liquidity which makes me feel secure and safe when trading with them. Furthermore, those two coins have been around the market for a long period of time, they also have really high value and doesn't pump or dump too rapidly. Especially right now, ETH and BTC is increasing!
