Well, technically yes but if you ask if I can always make them win? no I can't. Many professional traders or influencers share their tips and tricks on social media and recommend when to buy and when to sell. When they share something like that indirectly they make everyone who follows him will win in their crypto trading if his tips work well. But we never guarantee anything when we follow someone movement even our strategy will often be wrong. Don't be greedy in trading, because greed will only make your profit become losses in just one night especially when you trading altcoins.
