I bought Bitcoin because of the influence of my colleagues. I was too hesitant to buy it early in 2017 because I was still looking for proof that it's really a good investment but things have changed when the bull market happened last 2017 when I got a good profit out of it and I'm too grateful for it. I have sold my Bitcoin in 2017 and bought it again in 2018. I have sold some of it early this year and still holding some of it until now. There are still times that I doubt Bitcoin but I learned how to deal with the market's volatility.
