In the cryptocurrency world, do not trust any verbal promises; it's best to write everything down clearly. It might even be useless to have everything clearly written down. If you are in a weaker position, it's best to give yourself some sort of 'guarantee.'
Otherwise, after making money, you might very well be kicked aside by the other party.
Let's not even talk about promised returns; who knows, they might even try to find a way to get you in trouble.🤣
Always think from the worst-case scenario; let's not underestimate human nature.
