Buy BTC or other alts which haven't gone up $1 billion.
though i think those alts might never happen to reach such market cap any time soon most probably and it wouldnt make you a lot of money in the future i think though thats just my opinion
i think i would buy some ethereum then in order to make some big profit in the future if ethereum will start growing at a really rapid pace, in this way i would manage to make some good money i think
If the Ethereum does survive after the DAO crisis, that will be because of the big community support, the price will rise a lot.
