There are more or less three options to buy Bitcoins:
A. On an Exchange:
- Open an account on one of the hundreds of available Exchanges (google: Coinbase, Kraken, Abra, whatever you prefer). Also there are many exchanges that target local markets so if you are not in Europe or the USA you may want to find a local Exchange that provides smooth transfers of funds from a local bank account;
- Once you will have opened an account, get yourself verified (proof of ID and domicile are normally required);
- Transfer funds from your bank account to the Exchange;
- Once the Exchange notifies you that the funds have been credited, you can buy Bitcoins.
B. On Localbitcoins.com: open an account and arrange to buy Bitcoins from one of the many local sellers in your area. You can agree to buy Bitcoins in person or via bank transfer and your purchase is protected by escrow. This is very convenient but prices are normally slightly above the market.
C. Work in exchange for Bitcoin: you can work as a freelancer and ask to be paid in Bitcoins, instead of cash. I pay many of my contractors across the planet with Bitcoins, Litecoins and Ethereum and they are all very happy with this.
My advice is to stop the following bad habits:
- Stop keeping cash in your bank account: save money and, after you have set up a good emergency fund in cash, invest everything else in one or more low-commission, index-tracking, ETF funds, as soon as possible. The “VOO” (Vanguard 500 ETF) and “VIG” (Vanguard Dividend Appreciation ETF) are two good starting points. This must be a priority. Because compound interest takes time to produce its amazing results, the earlier you start, the better. (Since many asked in the comments, I also recommend to Google: compound interest + dollar cost averaging. In short: if you will be constant with this two-pronged strategy, you will do better than 90% of the fund managers worldwide.)
- Stop smoking, doing drugs, drinking alcohol: they do not add anything to your life, and only subtract cash from your bank account (that you should rather invest in ETFs).
- Stop watching TV: same as alcohol, TV does not add anything to your life. By not watching TV, you can spend more time reading interesting non-fiction books to educate yourself about the most different topics. Knowledge has a powerful compound effect: as you progress putting different knowledge eggs into your basket, your analytical firepower will gradually increase and the benefit that you will derive will be exponential. TV does not add anything to your knowledge basket. Sell it, and invest the money (either by buying ETFs or by buying many interesting books) instead.
- Stop eating outside: learn to cook your own meals.
- Reduce Social Media: remove the Facebook, Instagram, Twitter, Pinterest apps from your iPhone so that you can only access them via your desktop computer (you will automatically reduce your wasted time by at least 90%).
- Stop sitting on the couch playing PS4: it’s probably as bad as Facebook. Every time you want to play a game, go for a run outside instead.
- Stop surrounding yourself with all these fake friends you don’t care about: they don’t care about you either and they will dump you at the first time you will be in need. It is better for you to be prepared not to count on them (or on anyone, actually). Text/call/see your parents/grandparents more, instead.
- Stop shopping to impress or please other people. It doesn’t work. They will still hate you even if you have a new car or some ridiculous Gucci shoes. The rare, true friends will like you and be at your side regardless of what you own. Once you will start doing this you will learn that you are not what you own. Acquiring this mindset will free you from a thousand mental layers that cloud many of our life choices. It feels amazing.
- Stop accepting wrong things in the status quo: you can change things for the better. It just needs a brain and hard work.
- Stop being a cheapskate: show the fewpeople that matter to you how much you care about them. Bring flowers to your girl/wife/mum/grandma. Make a nice wedding gift to your best friend. Offer discreetly to pay a dinner out if your friend cannot afford. Be a gentleman for all people you interact with. Write a thank you card to a colleague who was helpful in a difficult situation. Be grateful, very grateful, for these good people that touch your life kindly. Do not be afraid to spend money for those who are important for you and deserve your attention, kindness and generosity. The sky will not fall if you spend money and give them your attention and, most importantly, they deserve it. I have seen countless of truly good persons being hurt, friendships broken-up in horrible ways, just because of people being outright stingy. Also, remember to give a part of your profits to a charity that is important for you: the good these people do to this world is invaluable.
- Stop not taking (calculated) risks: career-wise,with time we all get lazy and tend to accept the current status quo: our job, our boss, our colleagues, our commuting, etc. This translates into fantastic opportunities being lost because we are too scared to abandon what we consider our current safe harbour (which most of the times is not much more than a steady salary). If you hate your job, if every Monday morning feels sour, if at work you are not respected for who you are, if your boss does not appreciate your efforts, if you are not paid enough, if your last salary increase was ridiculous: these are all signs that should push you to reconsider your career choices and check if anything better is available on the market. Nothing out there? Not all hope is lost: keep in mind that there has never been a better time in the history of civilization to be your own boss and start your own business.
- Stop taking new debt. Ditch your credit cards. Pay all the new stuff you want to buy upfront. No exceptions. If you cannot afford something upfront, simply do not buy it (most likely you will not need it anyway). Same for the mortgage: rent / share a cheap place and invest your savings in stocks instead.
Edit: I revised point 5 in order to also include Instagram, Twitter, Pinterest.
