People saw crash as a bad thing for their investments. But some also sees it as an opportuniy to do their investment. When in times of crash that means all coins and other cryptocoins will be at a low price and that is the best timing to buy and hold until the price will rise up.
Many had time to bought coins at a low price during the fall and they now expect growth, which is slowly beginning. The bitcoin has already begun its growth, it remains to wait for the altcoins.
