If I were you I'll be diversifying my investment, not that I don't believe on ETH but just to be safe. I'd say, 40% for ETH, 30% for BTC, and 20% for other coins you think have the possibility to bubble.
I like this strategy the most maybe with a few minute alterations:
30% BTC, 30% ETH, 10% XMR, 10% BCH, the rest on "lotto" ticket cryptos:
ADA, EOS, NEO, ARK, TEL, etc...
