saving bitcoin in past has given me enormous profits and I am always stocking some coins because no one knows when the price might hike and give us big profit. Altcoins are good too 
Altcoins are really good at a moment so its good to put some money in altcoins and meanwhile let the price of bitcoins go higher so best thing would be investing money in bitcoins and holding them and trade altcoins to make quick profits and also to grow the level of bitcoins in our wallet.
