Poloniex provides only the basic tools necessary for competent coin trading. Before making trades, I always analyze the price and trading history – this is the minimum that needs to be considered. Trading simply by relying on luck means guaranteed loss of your deposit; it would be easier to just go to a casino. I don't limit myself to one currency; I use almost all of them, tracking which ones have dropped in price and buying if I see potential for growth. When the price starts to rise, I usually sell half of my coins, leaving the other half for the long term. In some cases, I use limit orders – then the currency is sold at the price I set when it reaches that level. So, if you're not confident in your signals, it's better to follow my example – make small trades that ensure even minimal profit. Trying to recover losses with 1-2 large trades is at least unwise.
