Lol BTC is not only for the rich, but for now it has gotten to a level whereby common people may not be able to afford it, so it is better to look for other things to invest in.
Right, those who say Bitcoin is only for the rich are very stupid and don't know anything about Bitcoin. Bitcoin is a decentralized currency, so anyone can purchase any amount of Bitcoin from anywhere according to their ability. There is no barrier to this: if rich people have more money, they will buy more Bitcoin, and if poor people have less money, they will buy fewer Bitcoins. Since Bitcoin is not controlled by any third party, anyone from anywhere in the world can purchase Bitcoin as they wish. Therefore, Bitcoin is universal.
