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.
The first stock market in the world was the London stock exchange. It was started in a coffeehouse, where traders used to meet to exchange shares, in 1773. The first stock exchange in the United States of America was started in Philadelphia in 1790. The Buttonwood agreement, so named because it was signed under a buttonwood tree, marked the beginnings of New York's Wall Street in 1792. The agreement was signed by 24 traders and was the first American organization of its kind to trade in securities. The traders renamed their venture as New York Stock and Exchange Board in 1817.

Equity investments historically have enjoyed a return significantly above other types investments while also proving easy liquidity, total visibility, and active regulation to ensure a level playing field for all. Investing in the stock market is a great opportunity to build large asset value for those who are willing to be consistent savers, make the necessary investment in time and energy to gain experience, appropriately manage their risk, and are patient, allowing the magic of compounding to work for them. The younger you begin your investing avocation, the greater the final results – just remember to walk before you begin to run.
A word on exchange balances: it is NOT RECOMMENDED to keep your cryptocurrency assets on exchanges. There are countless documented cases of people who lost access to their funds, either because their account was disabled, or because legislation forbade the exchange operator to give access to users based on their geographical location. Some exchanges have been hacked in the past and will be hacked. It is RECOMMENDED that you use your own wallets, that you secure them properly (more below) and that you limit the cryptocurrency held in exchanges only to carry the business/transactions you have to, and for the most limited amount of time, to reduce exposure.
Sell walls: the action of artificially keeping the price of a cryptocurrency asset low by placing a large sell order. Large financial operators or investors (nicknamed « whales ») may want to artificially keep the price of a cryptocurrency low so that they can keep accumulating quietly, without causing a sharp rise in price. These are called « walls » because on exchanges, the graphics showing offer and demand will show a very high « wall » on the offer size. The mechanism is that the investor will put a very large sell order (usually 100 to 1000 times more cryptocurrency units than regular orders). Because of how exchanges operate, the sell will only take place if there is sufficient demand to fulfil the entire order, so smaller operators who have a real need/urge to sell would have to sell below that wall (i.e. cheaper) to make sure they can get paid. This will cause a condition where the price will stagnate, allowing those whales to put as much smaller buy orders as they need. Sell walls may be removed once the buying whales have reached their objectives.
Phrases like “earnings movers” and “intraday highs” don’t mean much to the average investor, and in many cases, they shouldn’t. If you’re in it for the long term — with, say, a portfolio of mutual funds geared toward retirement — you don’t need to worry about what these words mean, or about the flashes of red or green that cross the bottom of your TV screen. You can get by just fine without understanding the stock market much at all.
Investment ideas can come from many places. If you want guidance from professional research services, you can turn to companies like Standard & Poor's, ValueLine, Morningstar, and other online resources. If the thought of spending your time browsing investment websites doesn't sound appealing, just take a look at your surroundings and see what people are interested in and buying.
On when to buy, my recommendation is to avoid jumping into the pump train when you see a cryptocurrency price rising very fast. Fear of missing out is a very potent psychological trigger for us humans and if you see something rising fast the first thing you’ll want to do is buy some so that you don’t feel left out. Go for the dip, but go for the dip reasonably: identify the cryptocurrencies you want to own, ideally solid ones based on your own research (it’s important not to invest in crappy projects), and when you see them taking the plunge go grab some big chunks.
You may decide to invest ad-hoc or on a regular schedule basis. You may for example want to invest 40% of your allotted funds into mainstream, “secure” investments such as Bitcoin, Ethereum or Zcash. You may decide to spread out the remaining 60% to cryptocurrencies listed in the top 20 or top 30 projects based on capitalization on coinmarketcap, if you feel this is a secure strategy.
Brokers are either full-service or discount. Full-service brokers, as the name implies, give the full range of traditional brokerage services, including financial advice for retirement, healthcare and everything related to money. They usually only deal with higher-net-worth clients, and they can charge substantial fees, including a percent of your transactions, a percent of your assets they manage, and sometimes a yearly membership fee. It's common to see minimum account sizes of $25,000 and up at full-service brokerages. Still, traditional brokers justify their high fees by giving advice detailed to your needs.
