In addition to knowledge of basic trading procedures, day traders need to keep up on the latest stock market news and events that affect stocks—the Fed's interest rate plans, the economic outlook, etc. So do your homework. Make a wish list of stocks you'd like to trade and keep yourself informed about the selected companies and general markets. Scan business news and visit reliable financial websites. 
Now, imagine that you decide to buy the stocks of those five companies with your $1,000. To do this, you will incur $50 in trading costs—assuming the fee is $10—which is equivalent to 5% of your $1,000. If you were to fully invest the $1,000, your account would be reduced to $950 after trading costs. This represents a 5% loss before your investments even have a chance to earn.

Finding the best stocks to buy and watch starts with knowing what a big market winner looks like before it takes off. As noted above, IBD's study of the top-performing stocks in each market cycle since the 1880s has identified the seven telltale traits of market winners. Your goal is to find stocks that are displaying those same traits right now. Traits like explosive earnings and sales growth, a strong return on equity, a fast-growing and industry-leading product or service and strong demand among mutual fund managers.
There are many fees an investor will incur when investing in mutual funds. One of the most important fees to consider is the management expense ratio (MER), which is charged by the management team each year, based on the number of assets in the fund. The MER ranges from 0.05% to 0.7% annually and varies depending on the type of fund. But the higher the MER, the more it impacts the fund's overall returns.
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.

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.

A stock is a type of equity investment that represents legal ownership in a company. When you purchase shares in a company, you become a part-owner. Corporations issue stock to raise money, and it comes in two variations: common or preferred. Common stock entitles the stockholder to a proportionate share of a company's profits or losses, while preferred stock comes with a predetermined dividend payment. When people talk about buying stocks, they're generally talking about common stocks.
Alternatively, you may be looking at digging hidden gems that may be well below the top 50 or top 100 projects, but still have a very solid technology or are undervalued. Doing your own research may help here, but of course it will require more investment and time spent, with a possibly longer ROI (Return on Investment) but the hope of higher gains.
Whatever happens on a stock exchange and no matter how much influence computers, algorithms and high frequency trading may have, human nature will always have an important role to play. Typically, human nature becomes more important when momentum is changing and there is excitement or panic in the air. It would seem wise to try and understand this mass psychology or group thinking which is often referred to by investors as the madness of crowds.

The biggest obstacle to stock market profits is an inability to control one’s emotions and make logical decisions. In the short-term, the prices of companies reflect the combined emotions of the entire investment community. When a majority of investors are worried about a company, its stock price is likely to decline; when a majority feel positive about the company’s future, its stock price tends to rise.

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.

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.
By understanding your risk tolerance, you can avoid those investments which are likely to make you anxious. Generally speaking, you should never own an asset which keeps you from sleeping in the night. Anxiety stimulates fear which triggers emotional responses (rather than logical responses) to the stressor. During periods of financial uncertainty, the investor who can retain a cool head and follows an analytical decision process invariably comes out ahead.

The exchange may offer privileged services like high-frequency trading to larger clients like mutual funds and asset management companies (AMC), and earn money accordingly. There are provisions for regulatory fee and registration fee for different profiles of market participants, like the market maker and broker, which form other sources of income for the stock exchanges.

Traditional full-service stockbrokers do more than assist with the buying and selling of stocks or bonds. They often offer a wide array of services and products, including financial and retirement planning, investing and tax advice and regular portfolio updates. But they can charge substantial fees and transaction costs that can erode long-term investment gains.
Like with the real world market, investing in a highly volatile market is a risky approach that can make you extremely rich or bring you to your knees. Besides the common sense approach to invest moderately (to limit the exposure of your other savings and personal finance needs), it is also recommended to spread the risk of investing in a volatile market amongst multiple assets.

Once you have a specific set of entry rules, scan through more charts to see if those conditions are generated each day (assuming you want to day trade every day) and more often than not produce a price move in the anticipated direction. If so, you have a potential entry point for a strategy. You'll then need to assess how to exit, or sell, those trades.

While some people do buy winning tickets or a common stock that quadruples or more in a year, it is extremely unlikely, since relying upon luck is an investment strategy that only the foolish or most desperate would choose to follow. In our quest for success, we often overlook the most powerful tools available to us: time and the magic of compounding interest. Investing regularly, avoiding unnecessary financial risk, and letting your money work for you over a period of years and decades is a certain way to amass significant assets.
