It's not a right choice to sell bitcoins, but is not illegal though.
I'm buying bitcoins and I'm waiting till the price grows. It can be higher price, I'm sure.
yes if one can bare to hold their bitcoin and not feeling the need to change it into fiat currency then he can really hold it, but as i have invested most of my assets in bitcoin so when ever i feel then need i use to change my bitcoin in to fiat currency and use it for completing my needs.
