New platforms such as altcoins, you mean? Anyone who get introduced to something new cannot easily trust that product or item, same goes with crypto. Especially with scam projects being rampant in the industry, researching is the first thing to do. With crypto, it's more of a gamble than investment, which also makes it more risky than stable. Do good research about a project before - its technology, the team behind it, and its benefits to the people. You can then evaluate what to do depending on what you  have learned and choose wisely. You can never truly trust a project or platform once you experience it, so do it with discretion.
