Get your funds in 50% bitcoin and 50% ethereum, safest strategy.
However, I don't personally think that BTC would go a lot down on 1st August, so don't at all convert all into ETH.
Bitcoin, as its nature, is a good one to invest and be safe in, but how about ethereum? I read the same things yesterday and I just can't figure out how you guys consider ethereum as a safe one. And you will put 50% of your funds in ethereum? Sounds extremely risky.
