you are saving a little amount,so i would recommend all of the money you have ,invest a little and save the left amount it can be use in emergencies ,earn little more and when you think you have saved enough then you can take risk of investing money in bitcoin.
Right. Rather than waiting for the moment to see where to put the funds, $200 is already a good amount to convert from fiat to bitcoin or any other cryptocurrency of choice as the case may be. If he had done that just in some few weeks back, without doing anything, there is already a huge percentage increase on the $200.
Who knows one day, it might turn to some big amount also and then the OP will be sure to gladly make use of it to do other things he would wish to.
