because after a few years, all your investments are going to be tripled or more than that. As long as you can buy bitcoin, just keep doing it and take advantage of the dip and don't listen to anyone that creates negative news about bitcoin and just keep on holding.
Actually, I keep my bitcoin on online wallet, its very easy to use. It's risk, but there is no problem for me because so much Bitcoin are not in my wallet and I don't think this Wallets will stop next years.
