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.
you can sell and buy bitcoins immediately on exchanges. There is already a huge liquidity in bitcoin markets, so it will take no time for your order to fill, unless you choose some limit orders
you can sell it to a trusted exchanger, such as bittrex, poloniex, liqui, binance, hitbtc, and more. for the time being, it's not so hard to sell the bitcoin we have, because it's available to be a happy assorted exchanger.
