Maybe moving some % of BTC into ETH is a good diversification strategy, while it's cheap?
No Way! I do not dare to invest in a currency that is doomed to failure.
And for those who advocate "DAO is one thing, ETH is quite another," well, if they were so different, is not being discussed a fork.
Currently, the best investment that can be made are innovative and promising currencies like the Decred, Vcash, etc.
