yes it is one of the advantages Bitcoin, but can also say the shortcomings, as you say can reach the highest price to that much, and can decrease until so low, but if you yourself smart predict you will benefit by the increase and decrease in price Bitcoin.
for the benefit I get from bitcoin can not be counted until now. because since I got to know Bitcoin, all the expenses I use are from Bitcoin. and it can not be denied anymore. How come. even to eat me with my family alone can be said in the outcome of Bitcoin. so Bitocin is like my life.
