Patience , maybe the shark are hungry for your coin, you should figure out what is the reason and make a right prediction after that. Patience is the key, don't be panic.
If you own no coins at all or sold all your coins, isn't this the best thing that you could happen? Thus like imagine you sold everything... now you have usd. Then you are ready to buy etc. Like i have btc. But other coins that i do not own but i want to invest, i want all those coins to drop down etc. Thoughts?
