I just say to those people that it is my asset ( investment ) which I am holding and waiting for the price skyrockets. I will not sell my funds I am holding till the price goes upto $1000 or more.
When the price of bitcoin reached to $450 from $380 within a week then there were some people who started to say that sell all of your coins as according to them it is the highest peak and after that the price will go down deeper, at that time I ignored theirnews and now I am saying to them that yousold all of your coins while I doubled my money with bitcoin from $380 to $660.
The price of bitcoin growing pretty good year after year, theres would be decrease of course, but price of btc will continue to increase, you can convert it some for buy something but to keep saving is the good investment, I agree with sell it when the price $1000 or more.
