Place it as a sell order on the trading book, above the current price. That way you are a market maker, and pay no fees.

50BTC is small potatoes, you aren't going to move the market.

Congratulations! Lucky you! You're a millionaire! Probably they were referring to an exchange site; the two most popular ones are Binance and Coinbase.
