one dollar is way too low to start investing. You have to always think that in order to make the energy and effort you put into investing worthwhile, that the return should be worth that energy and effort. If you want to invest one and multiply it, even if you manage to let's say make it hundred bucks, it's still not enough money to justify the effort that you've put into making that one dollar to a hundred. Does that make sense? You always have to find a good return to value ration, and if that is not reached the you should not invest in the first place. The risk to reward ratio here is way too low, there is no reward at all, and no risk at all which means that the investment of one dollar is not even worth considering.
