There's nothing totally safe in trading. Each and every trading is really and can be loss if you aren't capable to handle. Taking trading as a career won't be so easy one. Trading is kind of scientific method anyone must need learn the process and keep improving his knowledge if a trader must want get succeed. Otherwise start trading without knowledge will decrease your capital each time what i already experienced during I didn't gain single knowledge about trade but just started. And signal groups aren't always right even many time their signals proved as incorrect. You better you should have to learn to build up your own stretegy rather depend on other signals
Having a trading strategy is one of the best things to do but there are cases when our strategy seems to be failing and I think it wouldn’t be a bad idea to switch or get a better strategy but I’ve always know trading to be very risky and sincere nothing is guaranteed in trading, I think the idea of using only money we can afford to loss should always be preached because no one will bear the risk of your lost.
I agree with you that as a beginner, it should be advised to get a proper tutorship but it’s not also a bad idea to earn while learning maybe through copy trading.
