Bitcoin is cheap headed into 2019. It is the largest cryprocurrency by marketcap and the backbone of the cryptocurrency market.
Social media cryprocurrency sites including Steemit, Whaleshares, Trybe and Sphere Social rely on Bitcoin as a medium exchange. Traditional social media websites are the way of the past. Why post on Facebook or Youtube for free when you can get paid on Steemit?
What cryptocurrencies are you buying in 2019? For me its Bitcoin, STEEM and WLS.
