Hi I am a newbie and I am planning to invest ETH coin but I only have limited amount of money to start investing. Can I buy less than 1 ETH?Your response are greatly appreciated.Thank you. 
Yes, that's possible. I bought 0.2ETH last week on liqui trading platform and I used Bitcoin to buy it. You can also buy directly in USD, not necessarily buy with Bitcoin. There are some eth shopping sites or you can also contact directly to individuals selling Eth but be careful because scams are everywhere, you should consult others about their credibility before buy. Eth is now a very potential coin, if you intend to invest then you should buy it now
