First of all if you have friends dishing out bitcoins please can you introduce me to them. My friends only take off me never mind give me a bitcoin. On a serious note id say it depends on your current financial situation and also the reason he/she gave it you. If it was a gift with no preconditions and you are in serious need of cash, less a chunk of it. If it was to get you into crypto and you don't need the money, sit on it, forget about it and watch it grow!
