Experienced investors such as Buffett eschew stock diversification in the confidence that they have performed all of the necessary research to identify and quantify their risk. They are also comfortable that they can identify any potential perils that will endanger their position, and will be able to liquidate their investments before taking a catastrophic loss. Andrew Carnegie is reputed to have said, “The safest investment strategy is to put all of your eggs in one basket and watch the basket.” That said, do not make the mistake of thinking you are either Buffett or Carnegie – especially in your first years of investing.
Crypto-only exchanges do not handle any fiat currency, they don’t work at all with « real world money ». They will however allow you to trade a very large amount of cryptocurrencies. They have « markets », where you can exchange mainstream cryptocurrencies like Bitcoin (BTC), Ethereum (ETH) or Litecoin (LTC) for other less known cryptocurrencies. They will offer similar services as advanced exchanges but you will not be able to cash out. You would have to convert the cryptocurrencies you own to a more common one (BTC, ETH or LTC for example), send it to one of the fiat to cryptocurrency exchanges, and then transfer it to your account. Alternatively, you could also just decide to pay for goods and services in cryptocurrency. Or you could also withdraw the money via Bitcoin ATMs (where you send Bitcoin to an address and get cash, just like you would on a regular ATM).
Don't borrow money to use for stock market investment. On the stock exchange, borrowed money is known as either gearing or leverage. It is typically used either by companies (to help them finance growth), investment banks and hedge funds (to help juice their returns) or very aggressive traders. There are many spread betting (information here), options trading and day trading strategies that use borrowed money to enhance returns, but it also has a very profound impact on the risks being taken with each trade.

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.
Some countries also tax money that is sitting in exchanges under the form of cryptocurrency. The USA tax this as « investment money », i.e. at the price level that it cost you to invest. Example: 5% investment tax. You invested 350 EUR in cryptocurrency. Regardless of its value now (whether 1 EUR or 150000 EUR), you pay 5% on the invested 350 EUR. However when you cash out you will have to declare this as financial income.

Before you raise your hand to complain, yes, we know that a computer can track price changes much better than most humans. We get it. But the aim of the exercise is to get a 'feel' for the movements in price and that is unlikely to happen by using a computer program and pressing a button. We are talking here about stocks for beginners, and beginners need the learning experience, not the quick fix automation. Just trust us...


Following the first-time share issuance IPO exercise called the listing process, the stock exchange also serves as the trading platform that facilitates regular buying and selling of the listed shares. This constitutes the secondary market. The stock exchange earns a fee for every trade that occurs on its platform during the secondary market activity.
Those exchanges allow the purchase of cryptocurrency either via a card payment, or via a wire transfer / SEPA deposit from your bank account. They will also require some sort of identification because they are bound by financial laws related to customer due diligence and AML (anti money laundering) legislation. You may be asked to provide identification information such as an ID card, a passport or a proof of address. Note that some sites have different thresholds to buy cryptocurrency or withdraw fiat currency to your bank account based on the level of identification info you have provided. If you are into this seriously, make sure to provide the info necessary to the level you want to reach in time, not at the last minute when you want to liquidate your positions (or said differently, when you want to cash out).
Warning 2: this is serious. If you don’t believe me, just go on Reddit (r/Cryptocurrency) and look for posts of people who ask for help. There are some devastating stories out there which are all based on greed, credulity, inexperience and/or outright stupidity. You may become rich, but you may also lose everything. People are taking loans with high repayment rates to buy at peak price and will end up ruined. Young inexperienced people have burned their relatives’ lifetime savings, others have no money to pay their university tuition. Don’t be those guys.

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.
Instant-access exchanges offer speed and anonymity. You will most often trade your cryptocurrency against another at a fixed rate, but without the hassle of having to set up an account on a full exchange, without having to fund balances (you must use your own wallets – more on wallets below), place buy/sell orders, then withdraw to your wallet. You will have to provide two addresses (in cryptocurrencies, addresses are where your funds reside to make it short): a payment address (for the cryptocurrency you want to purchase, i.e. the address of your target wallet) and a refund address (the address from where you are sending the money from, in case the exchange order cannot be fulfilled. These exchanges are for example Evercoin, Nexchange, ShapeShift or Changelly (Changelly is not anonymous though). Some of those will even allow to purchase cryptocurrency with fiat currency.

You’ll come across an overwhelming amount of information as you screen potential business partners. But it’s easier to home in on the right stuff when wearing a “business buyer” hat. You want to know how this company operates, its place in the overall industry, its competitors, its long-term prospects and whether it brings something new to the portfolio of businesses you already own.
