I just drink untill I can't think.
(just joking)
That's the usual and saddest thing that people did when their getting regret especially when it comes to the important things to them, specifically when the price of the coin they hodl was dumped and not pumped anymore.
Instead of thinking positive and analysed the problem some of them are followed their emotions and contineous doing negative feedback.
I think that calm and regaining spirit to start new investment projects is the right thing to do instead of grieving and letting things go. The cryptocurrency market has great potential and many opportunities so I think investors should have a clear investment plan to minimize risk.
