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.
Now I know GE has been a dog for the last couple of years, shares are down 60% since the 2016 high. But management has made the tough decisions, selling off some assets and spinning off others. Cash flow is protected and I don’t think the market is giving the company credit for it yet. I think a solid turnaround in stock price could start in 2020 with even more gains over the next five years.

By knowing how much capital you will need and the future point in time when you will need it, you can calculate how much you should invest and what kind of return on your investment will be needed to produce the desired result. To estimate how much capital you are likely to need for retirement or future college expenses, use one of the free financial calculators available over the Internet.
In late 2014, legendary self-help and business guru Tony Robbins published a book called Money: Master The Game. In it he explains the strategies and ideas used by the very best investors in the world - hedge fund managers, asset allocators and billionaires - that he gleaned from them during four years of interviews and how their lessons should be applied by the rest of us.
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.
