50-50 is not a good idea, because if you get some profit in the other then it is less.
If you loose then the lost is small and that is good, but our concern is to win so i would go mostly 70% in bitcoin and the rest in gold.
This time is not good to take 50 : 50
i will take 75% for Gold ( because Gold price is down)
and 25% for bitcoin , you can see now bitcoin price up +20% from $220
That could be ok too, but i don't prefer to go 100% full to gold or bitcoin.
Only if you really think that the price will go up in near future then yes.
I still haven't bought gold, but maybe will think to buy at bitgold in near future.
