If i have 10000$, I would definately buy ethereum.Ethereum was the second breakthrough after Bitcoin, with their awesome smart contracts feature. There are currently at least 1,000 different types of coins as listed on various exchanges sites.Again ethereum price is relatively stable,bitcoin price can easily fluctuate.Ethereum is really cool to invest in.
I will invest mainly in bitcoin but not everything. I will also invest in ethereum because it is quite stable and I can rely on it
