Bob wants to buy Ethereum. He only has Bitcoin. On an instant-access exchange, he will trade Bitcoin for Ethereum. He will provide the target address of his Ethereum wallet to receive the Ethereum he wants to purchase, and he will also provide a refund address for Bitcoin, most likely the address from which he will be sending his Bitcoin to the exchange. Once he will submit the order, Bob will be asked by the exchange to send the necessary amount of Bitcoin to an address. Once he will send this money and it is confirmed, the instant-access exchange will handle all the buy/sell operations on his behalf, and will send the Ethereum once the order has been fulfilled.

If there are any lessons to be learned from the American sub-prime mortgage crisis, the 2008 stock market crash (information here) and Wall Street bailout that followed - and there are lots of lessons - it is that borrowed money can be very dangerous in investments, even when it is being handled professionally. The failure of LTCM, Bear Stearns, Lehman Brothers, Northern Rock and many others shows just how precarious a business model can be with too much gearing.
As written in section Investing 3, you should never keep any valuable assets on an exchange, unless you engage in day trading. You should get an appropriate wallet to store your cryptocurrency safely. To explain the concept better, what you are storing is not the cryptocurrency itself, but your private keys, the keys that allow you to spend the cryptocurrency that is assigned to you and stored on the blockchain of the given cryptocurrency (of course each project has its own blockchain, just like each bank has its own internal banking system – to simplify heavily). Anyone who has access to your private key is in control of your cryptocurrency assets, so you must secure them. Most if not all of the wallets around have a feature called a backup phrase. It is a mnemonic sequence of words that must be written on paper and stored securely. If you lose access to your wallet, get it lost or stolen or whatever, this backup phrase should allow you to recover instantly access to your private keys and funds, after which you should immediately transfer them to a new address.
For example, there may be three buyers who have placed orders for buying Microsoft shares at $100, $105 and $110, and there may be four sellers who are willing to sell Microsoft shares at $110, $112, $115 and $120. The exchange (through their computer operated automated trading systems) needs to ensure that the best buy and best sell are matched, which in this case is at $110 for the given quantity of trade.
And you can find such stocks in lists like the IBD 50, Sector Leaders, IBD Big Cap 20, IBD Long-Term Leaders, and IPO Leaders. For example, fast-growing semiconductor designer and artificial intelligence (AI) stock Nvidia was featured on the IBD 50 before it surged 750%. And Apple has been featured on various IBD lists as it has made big moves in recent years. While, of course, not every stock featured on an IBD list will make the type of moves that Nvidia and Apple have made, it does show why it pays to regularly update your list of stocks to watch using these S&P 500-beating screens.
Buy in thirds: Like dollar-cost averaging, “buying in thirds” helps you avoid the morale-crushing experience of bumpy results right out of the gate. Divide the amount you want to invest by three and then, as the name implies, pick three separate points to buy shares. These can be at regular intervals (e.g., monthly or quarterly) or based on performance or company events. For example, you might buy shares before a product is released and put the next third of your money into play if it’s a hit — or divert the remaining money elsewhere if it’s not.
