I sold my hero member account for 1 btc before 2 years but the fact is at that time the price of bitcoins was too low so I couldn't enjoy that profits as it was spent very quickly on my basic stuffs.
As long as you used that money for some useful things then no need to worry about it. Becuase no one can give any assurance that how the BTC price will go in future. That's we need to make a habit of saving bitcoins in small quantities every month for the long-term point of view. In that case, if BTC prices go up then we will have a lot of profit to enjoy.
