How do you know it's your best decision so far? Honestly it's not all about buying Bitcoin with the intension of holding but how to make sure you Bitcoin is safe and holding for as long as possible.
It's a nice idea that the OP purchased bitcoin, which I will commend him for that, but from the first thread that the OP created, he said he wanted to sell one of his phones, which he does not often use to invest in bitcoin.
support, advice and wonderful opinion.. I don't really know if the OP already has a job or a source of income from which he is making money, if he does not, I believe that he might end up selling the bitcoin back whenever he needs money to take care of other things. Since the OP already sold the phone and has already invested in bitcoin, if he does not have any source of income, it's better he get one.
