Hey I am still a junior member and I doesnt know everything about btc, I just want to ask that if ever we are going to sell our bitcoin, there will be an immediate buyer?? and where to sell it. please respect my post.
Lots of exchanger wherein you can sell your btc right away, bittrex, poloniex, etc.... You can also look for local exchangers in your country and convert it to your own fiat and then cash it out.
You can also sell it someone you know that wants bitcoin, like you relative, friends, companion or to someone you know but make sure that they don't scam you.
