A: This is entirely up to you and depends on your risk tolerance.
Trading microcurrency is more of a speculative endeavor than a traditional investment opportunity, so I recommend not trading with more capital than you can afford to lose.
As far as the cost per trade, most of these recommendations won’t require a great deal of capital to execute – many of the coins we’re targeting trade between a fraction of a penny and just a few dollars, so a modest investment can buy hundreds or even thousands of coins.
But be careful. Again, these are speculative recommendations. A good rule of thumb is to limit your speculative trades to 1% of your overall investment capital.
