There are three ways to go about buying Bitcoin and Litecoin.
Buy from a trusted friend or family member.
Buy from Bitcoin a Bitcoin ATM.
Buy Bitcoin from a cryptocurrency exchange.
The advantages of buying Bitcoinfrom a trusted friend or family member is obvious; no fees, no middleman and it should be a very fail deal. The disadvantage is finding a friend or family member that wants to sell their Bitcoin
The advantage of a BitcoinATM is that they are open as long as the store is open and they accept cash as payment. The disadvantage is that you may not have a BitcoinATM where you live, the fees can be outrageous, and there is some KYC*.
The advantages of a Bitcoin exchange are numerous; you can buy, sell and trade Bitcoin at any time and all you need is an internet connection. The fees are not near as high a BitcoinATM and the exchange will provide all sorts of features a BitcoinATM does not provide. The main disadvantage is you will have to provide KYC and there is usually more of a learning curve to using a Bitcoin exchange for the first time.
