Trading signals are best for newbies. With signals, you don't stress, instead it ease your trading. Although alot of scam groups are out there deceiving people and collecting money from them fraudulently. I was once a victim of these scam groups, which they swindle me of my hard earn money. Although that was when I was still a newbie in the space. There are legits groups giving trading signals which most of the trading signals are not guaranteed 100% correct. The trading prediction is under probability of 50/50 chance of giving you profit or making you lose your capity you invested. Although trading signals guide you not to loss 100% of your funds, it reduces losses but you should do proper research before paying for anything signal from any group no matter how legitimate the group is.
It does bring answers to many of newbies questions. All those "what should I trade" could be solved with it, get the top 100 coins and put indicators on them and then put notifications on it to let you know one reaches to level you want them to reach and then you can check if you want to buy.
I am not going to argue against the fact that people could make that kind of profit from these type of situations but the reality is that you can't really keep using that forever because it either doesn't bring you enough profit at all, or it does bring you profit but not a lot. This is why I doubt that it would really matter to people who trade for real, you want to find alternatives eventually.
