And what the reason ? It is very good that ethereum is cheap now for ICO investors, you can buy more tokens in dollars.
This is good only if Ethereum grows in price in the future, but it can become cheaper.
In a long-term Ethereum will only grow. Now 200$ is a very cheap price for EThereum, just use the moment.
Now is the time to buy it, so that later when there was a growth, you will get your provents, well, and as an option for investment in the project
Sure it is a big opportunity to multiple your dollars. You can earn both on Ethereum growth, and on tokens growth.
