For me ETH is the most potential coin to invest in currently. Aside to all other coins mentioned here BNB cannot be ignored as well. Most of the projects are still being launched on ERC20 network means people still believe that projects on ERC20 blockchain can attract more investors. I personally prefer ERC20 network for transactions due to its speed. Transactions on Bitcoin blockchain takes some time where as ETH network is very fast, current price of ETH is another reason to invest in it.
