Open mind and being able to question every thing that comes without being paranoid is what makes a investor diligent. Unfortunately in crypto things are no less than smoke and mirrors when it comes to altcoins and newly launched coins tokens or memecoins.

Things surrounding bitcoin are a bit clear, but even then the basic safety measures come before buying a coin. Most people dont have a safe device or are plugging in random devices on non-airgapped devices which have their passwords written in.

Those things are of utmost importance before starting to trade, which is again not everyone's cup of tea. Most traders try day trading and end up losing more they can imagine.
