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.
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.
Assess how much capital you're willing to risk on each trade. Many successful day traders risk less than 1% to 2% of their account per trade. If you have a $40,000 trading account and are willing to risk 0.5% of your capital on each trade, your maximum loss per trade is $200 (0.005 x $40,000). Set aside a surplus amount of funds you can trade with and you're prepared to lose. Remember, it may or may not happen.
History shows that investing in stocks is one of the most efficient ways to build wealth over time. Nearly every member of the Forbes 400 list of wealthiest Americans got there because they own a large block of shares in a public or private corporation. Learning to invest wisely and with patience over a lifetime can yield a portfolio far outpacing the most modest income.
Why I’m buying: Spell out what you find attractive about the company and the opportunity you see for the future. What are your expectations? What metrics matter most and what milestones will you use to judge the company’s progress? Catalog the potential pitfalls and mark which ones would be game-changers and which would be signs of a temporary setback.
