You will lose money if you do not use your head and just trade blindly. That is why there is called research and charts. You use them to predict properly and not trade no blindly. If you do that, the risk is lessen and it will not be too much of a gamble. You will be assured of profit for all your trade. Just do your work first before doing trades.
So meaning if a person is not doing his research and just follows what he reads in this forum when he wants to trade altcoins, can that be considered that he is gambling? I think it can be.
