Regarding your private keys, can either keep them on a software wallet, or on a hardware wallet. The software wallet is the easiest way for beginners, but it implies that you have a computer that is properly secured (strong password, antivirus etc.) and that you do backups of your data. Remember, if you lose your private keys, the money is gone forever. As you get into cryptocurrencies more seriously, you will inevitably look for a hardware wallet, which is a dedicated device resistant to hacking where you can store your private keys (or to say it in an easy way, your crypto assets/invested money). I have already written an article on a hardware wallet, the TREZOR (see here). The most common wallets are the TREZOR and the Ledger Nano S. The TREZOR has a new model being sold from January 2018 (Model T) which will support much more currencies than the current TREZOR. The Ledger Nano S has more integrations currently, but I would recommend to wait for the TREZOR T to judge properly. Those devices usually cost around 100 USD, so once you have more than 100 USD to protect it starts making sense to get one.
Every online brokerage firm on the list above has its strengths and weaknesses. It might be ideal for one customer and at the same time might not work for someone else. Before opening an account, there are a lot of parameters to consider besides commissions, well-known brokerage name, and pretty website. Some of the most important of these parameters are surcharges and fees; friendliness to client's knowledge level (perhaps one is a beginner? or needs a professional-level trading platform?); availability of investment products a client wants to buy (for example forex, futures, or NTF mutual funds) as well as availability of online community, virtual trading, and discounts. We suggest to investors to take a time to read brokerage reviews, and see for themselves if a particular firm is the right fit.
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).
You may see a number of sales charges called loads when you buy mutual funds. Some are front-end loads, but you will also see no-load, and back-end load funds. Be sure you understand whether a fund you are considering carries a sales load prior to buying it. Check out your broker's list of no-load funds, and no-transaction-fee funds if you want to avoid these extra charges.
Blue-chip stocks—which get their name from poker, where the most valuable playing chip color is blue—are well-known, well-established companies that have a history of paying out consistent dividends, regardless of the economic conditions. Investors like them because they tend to grow dividend rates faster than the rate of inflation, so the owner increases income without having to buy another share. Blue-chip stocks are not flashy, but they have solid balance sheets and steady returns.
Stock brokers are people or firms licensed to buy and sell stocks and other securities via the stock market exchanges. Back in the day, the only way for individuals to invest directly in stocks was to hire stock brokers to place trades on their behalf. But what was once a clunky, costly transaction conducted via landline telephones now takes place online in seconds, for a fraction of what full-service brokers used to charge for the service. Today, most investors place their trades through an online brokerage account. (A little lost? Check out our explainers on brokerage accounts and buying stocks.)
What would make me sell: Sometimes there are good reasons to split up. For this part of your journal, compose an investing prenup that spells out what would drive you to sell the stock. We’re not talking about stock price movement, especially not short term, but fundamental changes to the business that affect its ability to grow over the long term. Some examples: The company loses a major customer, the CEO’s successor starts taking the business in a different direction, a major viable competitor emerges, or your investing thesis doesn’t pan out after a reasonable period of time.
