When I first got into cryptocurrency, I came across a lot of scams. A few happened to get me, ultimately teaching me the lessons and how to avoid and keep me a steps ahead of scammers, never take anyone who contacts you first serious online, and secondly dont trust anyone with your cryptocurrency assets in the form of third-party holding or investments that promise high returns
To add to this, don't also trust the offer and idea of a shiller who recommends a project which they consider to be the best one to invest in, as they have nothing to lose but shill what they can benefit from. Online scams are just in different forms; we can never be too careful, but if we are observant enough, we can avoid falling victim to most of them.
