If that means you currently have a good amount of bitcoin in your hand and you're finding a buyer, I don't think the forum is the place to be. You can do it on other platforms where you can see and observe if the buyer is really trustworthy. Considering the fact that you are just new in the forum, I don't think it is a good idea that you get yourself involved on trading or selling already. No matter how high your current holdings are, you will just end up putting into risk and you might end up regretting it in the future so always make sure that you think wisely before making a step.
