Is it worth investing in Ethereum today? I would not doubt it for a moment, the price did not fall to such values a YEAR!! This is a very good price to invest in Ethereum. In the future, it can grow by hundreds of percent. When the market turns green and Ethereum-based ICO becomes popular again, its price will rise and you'll be biting your elbows and remembering that time with regret that you didn't buy Ethereum.
