BitCoin is very dangerous as it is not backed by anything tangible. US dollars used to be backed by gold, but that's another story altogether. Many big BitCoin owners I know are now taking their money out of BitCoins and purchasing silver. Silver 1oz coins are a favorite, as are 10oz and 100oz bars. Today silver hit 17.00 per oz. It is heading to $25.00 per ounce and many believe that 100.00 to 200.00 is not out of the question, in the near future.
You can hold Silver in your hands and keep it in your home. It can be stored in a safe or other secret spot.
BitCoin value could crash overnight and is expected to do so soon. Move your money to silver asap, to avoid a huge dip in your assets. Buy BitCoins again after the bubble bursts.
