Bitcoins can be purchased at the following places:
Over the counter: This means buying bitcoins from another person directly. Although this sacrifices the anonymity of a normal bitcoin transaction, it is still very popular. There are many websites that connect Bitcoin sellers with buyers, like Binance.
Bitcoin ATMs: These look and act like regular ATMs, but instead of receiving cash, you get a receipt with a designated code. Scanning this code adds bitcoins to your wallet.
Free Bitcoins: You can go to our faucet site Coinbox and claim free BTC and other cryptocurrencies (ETH, EOS, USDT, etc).
