Falling is not a bad thing, its bitcoin nature falling down the price and go up again, and this is the time to buy bitcoin, till the price is low. Because im sure it will rise up again. Just hold it and wait.
For sure it is good to see the price change in bitcoin because it is having very high impact on the life of an investor, we should wait for the price of bitcoin to increase very high, let the market rise if once it decrease and if you want more profit from it them try to buy at low price and then I say you should wait after buying for long time, so its really natural dont be worry about this fluctuating nature of bitcoin.
