So within the last few months the amount of publicity surrounding Ethereum ICO's has grown significantly. A lot of people seem to think that is a large indication of a bubble however I see it as an opportunity for Ethereum to solidify it's worth amongst other currencies such as Bitcoin and Ripple.
In the months to come, the outcome of these token sales will inevitably determine the Ethereum ecosystem for the next few years . The main reason for this is that those invested in these tokens, will also by association be supporting the Ethereum blockchain. So essentially it means the distribution of these tokens will add value to the overall Ethereum blockchain over time and the creation of more dApps/smart contracts on this chain will, hopefully, create more value for Ethereum itself.
However this isn't without it's problems, at the moment there is concern over a growing amount of centralisation in terms of Ether amongst token holders and the Ethereum foundation. These token holders now hold the responsibility of ensuring their investment in the Ethereum ecosystem remains secure for years to come so I don't think this is a major concern at this point but it is debatable. As well as the currency itself is still in it's infancy being only a few years old, it still has a lot more room to grow and change.
