This is totally a simple work like simply buy things at low price and sell at high price .
But here we are small with different concepts that most of the times we seen big dump and big pump , so here more chances to make bulk and more chances to loss also .
So here if we buy any asset then after the dump we may need to wait for long time i.e have lots of patience .
For better trading experience I would like to recommend you for the trading at poloniex , bitrex , binance ( Handel through mobile ) .
Here one another suggestion for you from my side is that don't go for the attention towards negativity about cryptourrency and always do your work with lots of patience .
