There are several ways to sell Bitcoin. But it seems to me that the most optimal is the sale of cryptocurrencies through the sites of online exchangers. To find an exchanger, I use BestChange. Here I found an exchanger to buy and sell bitcoin https://www.bestchange.com/bitcoin-to-paypal-usd.html The table at bestchange shows the best exchange rates for the 20 most popular directions, with the best rates on top. Other relevant information is available in icons next to the exchanger name and columns to its right.
