The simple answer of your question from my opinion is YES! Around $200 is the bottom of ETH so the buy between $160 - $200 is best buy I think. A new rally may reach it top to $800. November is coming! Many surprises and the positive news will affect the price as well. I am suggesting that the investment is ETH is no doubt beneficial but you may consider few project based on the ETH blockchain will be rise as ETH grow in the value. There're so many project build on the ETH blockchain, you may research first before the investment you may get huge profit. Happy Trading!
