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.
