Fortunately, at least in the United States, investors do not have too much to worry about when it comes to account security. This is especially true when choosing a brokerage that is large, well known, and properly regulated. Every website should be secured with SSL encryption, and client data should be stored in secure servers. Dual-factor authentication and Face ID are other security protocols quickly growing in popularity.
Comparing the cash flow statements of companies is going to help you narrow your list down even further. So you’ve found a few sectors that are really going to benefit from these broad themes, that’s step one.

The challenge with Bitcoin and Ethereum these days is two-fold: first of all, both networks are congested with very high utilisation. How does that impacts us? Congestion means that there are more transactions to be processed than the system can actually ingest, which leads into transaction queuing. This means that those transactions will go in a wait list to be mined, and that means that it can take at least 20 minutes to a few hours for your transaction to be confirmed – a confirmation meaning that the transaction has been validated in at least one block. Going with BTC or LTC may result in longer times to get your money effectively transferred from one place to the other (for example if you want to store it securely on your wallet, or if you need to send it to an exchange). For transaction speed I prefer to go with Litecoin at the moment, except in cases where Bitcoin is still more advantageous. Keep in mind that despite the huge transaction fees Bitcoin sees massive adoption and has the first comer advantage.
Preferred stocks are very different from shares of common stock most investors own. Holders of preferred stock are always the first to receive dividends, and in cases of bankruptcy, will be first to get paid. However, the stock price does not fluctuate the way common stock does, so some gains can be missed on companies with hypergrowth. Preferred shareholders also get no voting rights in company elections. They're a hybrid of common stock and bonds.
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.
