The common assumption that Bitcoins are stored in a wallet is technically incorrect. Bitcoins are not stored anywhere. Bitcoin balances are kept using public and private “keys,” which are long strings of numbers and letters linked through the mathematical encryption algorithm that was used to create them. The public key (comparable to a bank account number or IBAN) serves as the address published to the world, and to which others may send Bitcoins.

If you have a brokerage account, you can expect the bitcoin user experience to be similar. And, as with a brokerage account, you’re likely to pay transaction fees whenever you buy or sell. That means day-trading bitcoin probably isn’t a great strategy — since those transaction fees could quickly eat up any profits. If you’re using bitcoin instead of PayPal, Venmo, etc., check first to see if the seller will charge you a fee for paying in bitcoin.

In 2017, the Bitcoin project and its community split in two. Perhaps the least controversial way to refer to each side is simply by their respective ticker symbols, BTC and BCH. Bitcoin Cash is usually represented by the BCH ticker symbol and is considered by its supporters to be the legitimate continuation of the Bitcoin project as peer-to-peer digital cash.


Bitcoin has captured America’s imagination. Whether or not the cryptocurrency will ultimately turn out to be a good investment or just a passing fad remains to be seen. Indeed, in the past several months Bitcoin prices have enjoyed a run-up that makes the 1999 tech bubble look staid by comparison. That excitement — the promise of sudden riches or sudden ruin — has a lot of people wondering how a bitcoin investment actually works.
To receive payments, a wallet will usually generate a new address for each transaction. To send payments, the wallet will digitally sign transactions with the correct private keys and broadcast transactions to the bitcoin network. Once a transaction is confirmed by the network, the wallet will no longer be able to spend the same bitcoins used in the transaction again.
Notice that Craig Wright has made it clear that he is willing to “sacrifice” and even if it will cost him money, he shall channel everything they got to see BCHSV go live. That means, in the run-up, uncertainty reigns. As such capital could flow out of BCH further exerting pressure on the coin. In that case, depending on the exchange, traders should hold off trading aware that losses below $400 shall inevitably ignite sellers aiming at $300 or BCH all time lows.
Maybe only one coin survives the split. In that case, wallets and other service providers will presumably support this coin, either right away or later on. If you hold your private keys and your wallet supports the coin, you will be able to transact. If your wallet does not, you’ll need to extract your wallet seed or private keys and insert them in a wallet that does. (There’s no rush to do any of this.)
Coinbase Pro expands on these basic capabilities. Coinbase Pro offers options to make market orders, limit orders and stop orders, to buy and sell. Instead of trading exclusively from USD to a given crypto, Coinbase Pro allows users to trade between cryptocurrencies (so, selling Ethereum for Bitcoin, for instance), and in different currencies (USD, EUR, GBP). Like Coinbase, the cryptocurrencies available for trading on Coinbase Pro are Bitcoin, Bitcoin Cash, Litecoin and Ether.

On Aug. 1, some miners and developers initiated what is known as a hard fork, effectively creating a new currency: Bitcoin cash. Bitcoin cash has implemented an increased block size of 8mb, to accelerate the verification process, with an adjustable level of difficulty to ensure the chain’s survival and transaction verification speed, regardless of the number of miners supporting it. This has raised concerns about the security of Bitcoin Cash.

In mid July 2017, mining pools and companies representing roughly 80% to 90% of bitcoin computing power voted to incorporate a technology known as a segregated witness, called SegWit2x. SegWit2x makes the amount of data that needs to be verified in each block smaller, by removing signature data from the block of data that needs to be processed in each transaction, and having it attached in an extended block. Signature data has been estimated to account for up to 65% of data processed in each block, so this is not an insignificant technological shift. Talk of doubling the size of blocks from 1mb to 2mb in November has ramped up, and is expected. This would also go some ways in improving bitcoin’s scalability. In mid-October, Bitcoin scientists from Bitcoin Unlimited revealed they had mined the world's first 1GB block, 1,000 times bigger than the normal size. 
To sell your Bitcoin or other cryptocurrencies on an exchange after purchasing, just go to the appropriate page or tab, for example, Coinbase has a Buy/Sell tab where users can buy and sell on the same page. Most exchanges will charge a fee for selling, usually around 1%-2%. The exchange CEX.io will allow users to sell Bitcoin and receive funds directly to their credit card.
