For example
If i need to trade on LTC (Litecoin)
Its better for me if i need to trade
In both cases
When prices UP and When prices DOWN
To trade by currency pair (LTC/USD) or (LTC/BTC)?
When LTC is High, convert to btc because you the possibility of getting most profit is high. Bitcoin will also increase at time like that. When you directly convert to btc, the profit is stock to that price and in lesser risk. While if you convert it to btc first, there is a higher risk and at the same time, a chance of getting a bigger income because of bitcoin's price changes from time time even if you already converted to it. Your amount on hold is affected by the change in bitcoin's price. But still, there are many choices and opinions out there, so take time to read and compare to see which idea is the best. Good luck.
