I have fallen out of the bitcoin world many months back. I'm starting to think the dust has settled now.
I setup coinbase to buy $10 a day of the next year and a half until the next block halving sometime in 2016.
I going to go about my business. No investing in miners, altcoins, etc, etc, etc. I am simply just going to try and forget it.
This is safe strategy, if you really believe with your strategy, add more your invest for more profit i think.
And yes invest in another crypto coin is more risky especially with investment which can double your money easily.
