Knowing how to buy or accumulate Bitcoin is one of the first thing you should know when starting Bitcoin investment because it is very necessary and buying from exchange and sending to your private wallet will cost you some unnecessary fees and so to avoid or prevent that you should meet someone that can teach you how to go about it, you can only reveal your private details to someone if you showed the person your device while login and to avoid revealing it, you can login before meeting the person or the person can still use his or her exchange to teach you how to do it.
In as much as I will love to say the money you are using is small, I will also want to congratulate you for starting first at least and I want to believe this $10 is what you can afford to let go and $10 means that your sources of income is very small but it doesn't matter how small you start what matters is how you will end, your consistency.
If a new investor has basic knowledge about Bitcoin, and has faith in Bitcoin, then he can invest, and can also be successful by investing.
For a new investor to be successful in his Bitcoin investment, he must approach the market with a long term plan while understanding the key factors in Bitcoin investment which is consistency, patient and risk tolerance. The more quantity of Bitcoin an investor can stash matters a lot because that is his main goal,to focus on accumulating more bitcoin consistently into his portfolio with DCA while building his Emergency funds simultaneously. Emergency funds is kept for real time emergencies or unforseen occurrence,so as to help him not to tamper or sell parts of his portfolio when he needed not to. The market can be volatile and sometimes unpredictable,a long term plan is considerate as the right approach for a new investor because you he doesn't need to bother any more with fluctuation of prices of bitcoin as he is already on a long term plan to invest and to Hodl for a substantial period of 10years and should only be focusing on his accumulation pace until he reaches his desirable accumulation target.
