I don't use use my bitcoins. I am thinking to hold it for a year or so to see what happens. But my amount is not any near of yours. I think holding now is the best way to grow money
No doubt again if hold the bitcoin is the best strategy for get more profit, a week ago the price was about $1000 but right now the price was more than $1200. Many people panic when prices are declining and see the graphics but if they be patient then we can get more profit.
That is a strange reality that even after knowing the fact that price volatility is very common in bitcoins people gets panic when they see downfall in the price of bitcoins and start selling their coins at cheap price instead of holding them till the price bounce back once again.
