Ethereum is more stable than any other Cryptocurrency. Many Ico projects create an ERC20 token and use Blockchain Ethereum for smart contracting. While the situation will be the same, the price will remain stable. Save options You can invest in Ethereum but please do not use hot money, just invest for something you can afford to lose. Give the rest of the money from your salary.
I do not agree with you. Ethereum also fell in price the same way as all other crypto-currencies (in January the price reached $ 1,200, and then it dropped to $ 400). Therefore it is wrong to say that Ethereum is a stable coin. Invest in Ethereum is possible and necessary. Its price will definitely grow.
