Instead of looking at those dips negatively, look at it on a positive way. I remember reading somewhere that if see the price of Bitcoin dropped, buy more, if you the price of Bitcoin dropped some more, then buy more. Look at what happened last Monday and Tuesday, price of BTC dropped 16% but recovers after 48 hours. Think positive and don't panic.
It is very difficult to stay calm when you see how fast your cryptocurrencies go down. However, I can cope with my emotions. Simply think about the time when the market will go up.
