I believe every Shib holder with diamond hands will be happy. Everyone has there own plan with what they want to do with their Shib and that’s how it should be. I can’t answer the question. The only way I can partially answer your question is by experience with the very first crypto I bought last February and still hodling and that is “ I wish I bought more” before the price went up.
That answer will be different for everyone. I would at least double that bag, then when it moves big, remove your investment so you can ride the balance at no cost to you.
