I think for someone who has been in the Bitcoin investment for over 3-4years now, I don't see any reason to be scared of the dips. It's not something any one should actually be scared of, it doesn't matter how long you have been holding. The amount of Bitcoins you hold today will remain the same tomorrow and in the future. Just the value in the market changes due to volatility nature of Bitcoin and many other factors that influences it's price. There's nothing to panic about. Just use every dip to accumulate and hold even more BTC so when the price might return to a bull season, you would be filled with joy of a holder.
