Need help on my money tree

[Shui1983]

I bought my plant from IKEA. After few weeks, I realised the leaves are curl down. I guessed it may due to the small pot. So, I changed it to a bigger pot. However, it did not turn better but worse. Some of the leaves are even turn brown. It looks like dieing soon. Can anyone please help me?
