Two years ago when bitcoin price is around $ 400 , I bought 5 bitcoin, a few days ago I sold 3 bitcoin for more than $ 3000 each, so I got profit $ 7000 and I still have 2 bitcoin.
somebody which holding Bitcoin at 2009 until now will be the billionaire because they can very high profit. Imagine if they buy Bitcoin at $ 50 and holding up until now, How much profit? I think you know the answer.
and I laugh when hearing someone buy a pizza with 10k Bitcoin.
