Thanks for everyone's great advice. I had put more into LTC as i heard there was going to be an impending 'pump'. Might give it a few more days and then move some back into BTC and ETH 
Oh man. Be careful.
If you are going to implement a trading strategy you need to spend weeks if not months thinking about it and maybe running through old data to make sure it makes sense.
I was thinking about the correlation of LTC to BTC and how it might slipstream it, but this last week has completely changed that for me.
These cryptocurrencies are new beasts and are easy to manipulate by whales. Even stocks and commodities can be manipulated by Reddit these days.
My strategy is just to buy little bits of things I like and hold it. When I feel like it.
Don't try and actively rebalance crypto, for that way madness lies.
