How serious are you about this?

Fact of the matter is that if you buy ETH now and look away for 6 months, you'll make more money % in most other investments. Of course that's boring.

The top 10 market cap coins have a hard time dying if just because of the volume by active traders accumulated. They are all fairly "safe". Platform tokens (ETH, NEM, NEO, WAVES, STRATIS, LISK) will also not die off quickly, because external events can raise their value.

For the first 2 weeks, you can stay in $. In general, if you want to go beyond investments, if you want to accumulate G worth on the coin, and the fee at your exchange is F, you can buy A amount at a price P and set a sell off at price
P' = P · (1+G/100)
and
A' = A · (1+2F/100) / (1+G/100)
So e.g. if you buy A=1ETH at P=300$ and want G=4% and the fee is F=0.25%, you set a sell order of
P' = 312$
where you sell
0.966 ETH.
This way you get your 300$ back, pay about 1.5$ fee and accumulate 0.034 ETH, which is about 10$.

He's talking about trading not investing. Even if eth does go say 2x in the next 6 months, you can make that much by day trading if you're experienced and lucky, since a lot of coins get pumped on a regular basis.
