Choose a good platform to trade and good coins to trade for. Once you establish that, then at least you know where you would do business and what coins you would look for and be after. Next to consider is the amount of capital you would shed, would you use a big capital or a small one. That would then affect what kind of coin you would be trading for, if you would focus on those high-value or low-valued coins. The main difference is with low-value coins, you can get more of them for less money unlike with high-valued which even a big amount won't give you that much. After that, set your goal or profit margin in trades, which ones to hold and which ones to immediately dispose.
