That moment when you buy 1BTC at $2500, and then 3 days later someone buys it at $2000. But I'm guessing that it's the risk involved in investing, so what do I do now? Sell? Or hold on them?
I hope you are still holding that bitcoin, just look at the prices today and it will surely make sense why most people tend to hold their bitcoins. Bitcoin price will surely goes up in the years to come so it would be to your advantage to just hold that coin that you bought.
