OP, if you have enough money to buy bitcoin, don't just spend it or make a rash decision. We all know that investing in bitcoin is good, but you still need knowledge and the right timing to do it.
Well the guy's willing to spend 5k in bitcoin. It's okay to ask other people's opinion, especially here where a lot of people can be considered as experienced traders and crypto users for the longest time. I think the question is pretty simple as to where he can get btc with his funds. He probably has an idea but want other people's suggestion as well. The only thing for me is, don't base the decision on what others say. Keep their tips in consideration but make your own decision based on your own research and study.
