I think the benefit of cryptocurrency trading is a lot if you have experience in trading. You can make a lot of money from trading if you invest in potential cryptos like BTC, ETH, XRP, EOS, but the risk is very high, you can lose all your assets if the crypto you invest is the bad coins.
Experience and knowledge are both to know when come in the world of cryptocurrency, when don't have both those, then you will lose your time and money. No bad/shit coins when developer have seriously to developing them, like you explaining them.
