If the price of bitcoin is not falling than we can use alternative coin which are more stable than bitcoin and use them instead of bitcoin.
For those who have not bought it yet, an altcoin can be a good investment. But who already bought bitcoin, I suggest hold and wait. Selling now because it's falling, it'd be crazy.
True, you haven't lost anything if you are just hodling your coins, for me the worst idea now could be to just sell anything you have, there is still lots of chance that market will get on a good way again.
