I just sit and drink coffee robusta 
There's nothing I can do when the market situation is like now, waiting is a good thing for me, because the portfolio I have is already minus more than -60%. I wish I could do DCA, but I didn't, because I was looking for new tokens with low MC to earn $10 to $15 a day.
Keep calm to face this current market condition , when bitcoin is struggling and going down, almost all of altcoin will go down.
Sit and enjoy your robusta coffee, it's good way to do.
I have another hobby, go to farm and sometimes have music.
Not easy to predict what will market go.
Keep hold and hold, I just do it
