buying bitcoins is for get profits from make trading with altcoins
also for future investment still believe bitcoin price will more high & high future
buying bitcoins is a long term strategy to make a good profit
I'm guessing most bitcoin users are buying/holding bitcoins for profit in the long run because looking at the past, we can obviously see just how much bitcoin has gone to. In the near future, bitcoin would surely be of higher value that what it is right now.
To earn higher profits from it you should hold it for long term, as price will be beyond our imagination in next 5 years so if you can afford to hold till that time that it will be the best financial decision of your life.
