Keep calm and hodl!
Standing 100% behind you on this one. No point in panic selling now, just to buy back the coins in a few weeks. Rather than selling into the dip and make things worse I want to buy more coins. The first thing I did this weekend was to withdraw some of my poker money and put it into bitcoins. It's not realistic to sell now and hope to buy back at 20,000 or 10,000 level. When it comes to HODL investing it means to hold when the price rises and when the price falls. We need to remind ourselves that HODL was one of the most successful strategies over the last few years. There is no reason to abandon it now.
