I don't also like Bitcoin's price volatility due to the fact that you could lose your investments quickly. This is a disadvantage but it also serves as an advantage since you could take advantage of price's instability (volatility) and make profit if you know how to do it well. Over the past weeks, I have been doing this and have made a decent amount of profit.

I also think  that there aren't much merchants accepting BTC but if you take a look, it is slowly gaining its adoption over time and I think it would take 5 to 10 years to see true mainstream adoption.
