I have positive perspective about the situation but I don't have balls to say people "sit, wait and keep losing, everything's gonna be alright". You say we saw dips. I'm sure you were saying same thing 3 months ago. What happened? Most of coins decreased %70-80 more. So you can be optimistic but shouldn't be ensure prices are not going down anymore.
In a situation when all the coins in the portfolio have fallen in price by 70-80%, it remains only to wait for the situation to improve and the market to grow. I am an optimist, I am sure that growth will begin, only I cant name the time when it will happen.
