That is exactly what I am saying, there are some risks we take which we are not in anyway supposed to take. Everything is all about wisdom and knowledge, before you think of investing on something or or spending your money on something, just have to be calculative.That is true, some risks are just not worth it and may end up costing you more. If you have spare money that you wont have use for and you know that investing it will not break your heart when you lose it, then you can take the risk, even with that, still take a risk that you feel will yield enough profit when it grows.
