I think placing all of your funds into bitcoin is a dangerous decision because right now bitcoin is down and we do not even know when it will rise up again , so i think it is better to monitor bitcoin for now
Yeah i think no one take that much risk by adding his or her all funds in Bitcoin because no one knows that when Bitcoins price will rise or go deep down.It's better to divide all your funds in some AltCoin like adding some funds in Eth and some in other altCoins Or trade to make profit.For me i never hold my bitcoin in my wallet, i transfer all funds in my bank on same day.
