Thanks OP. I bought a lot in 2015 and 16 and held ever since. I held all the way through 2017 peak to the 2018 low of 3k, without selling a single coin. Let's see how far we'll go this time, but I think I'll sell at least 1 BTC now to celebrate those years of holding and have some fun. The rest will wait for another milestone like 50k, when I'll have another party at Bitcoin's expense. Long live bitcoin and good luck to all hodlers! 
if you can survive and don't sell 1 Bitcoin you are very good. Someone will be mentally shaken when holding for a long time. Especially when the bitcoin price starts to be bearish at the lowest price below the price you bought at first. Holding is a very appropriate strategy for people who want to invest in bitcoin for a long time but get a lot of profit. But Buying bitcoin must also be at the right time in order to get a cheaper price.You now have a new goal of reaching the $ 50k price tag. That's pretty awesome, but the $ 30k ATH is still waiting for now.
