I turn off notifications and go to sleep or enjoy my day. Over the years I've learned that it's better NOT to do anything at all if things go down because in the end they come back up. Sure, this doesn't work for shitcoins but if you have your money into proven coins, it's always best to just wait.
There's a quote that circulated on twitter recently, time is everything, timing is nothing.
Nice quote and exactly right, time is everything. But I need to admit my timing could be much better in terms of my trading behavior. It is not easy just to stay calm, when you see everything dropping and you do not exactly know why.
