65/25/10 investment split.
65% into safer cryptos - ETH/BTC (you will know if hard fork for BTC will be an issue by then)
25% into mid-safe cryptos - research which ones stabilize in August (Golem/Siacoin etc.)
10% into ICOS (initial coin offerings) which have the chance to make a high ROI; Status, Civic and in the past Bancor, BAT, Aragon etc.
