Yes it is still worth to trade but for now since the bitcoin value is high its price you may earn a little profit. You may search for an altcoin which buy at lower price and sell it if earn profit already. So for me its still worth to trade as long you invest and be profitable.
Profiting through trading is quite good and worth depending on the person who involve into it. Trading has got risks and with simple concept one cannot profit high through trading. One needs to be good in making the price predictions in a better way as well needs to spend time on price analysis over a period of time. This will help to fix the profit margin and make good earning even if there is not much fluctuations.
We all know that in trading the risk is always present. Whether you just invest a little or big amount you can't be sure that you will profit. However, if the person wants to mitigate the risk, then one should start trading with amount that you can only afford to lose. And then gradually increase you investment as you become more experience in reading the market trends. So the more experience you become, the more chance of you profiting big amount making you a professional trader. Making trading worth of your time and money.
