You have a lot of ways to increase your Bitcoin. One way would be Trading it but I highly recommend to educate yourself first before you start trading any asset. You can also Lend your Bitcoins on Exchanges like Binance and Poloniex to people which create Margin contracts and if you catch a good time you can increase your Coins nicely there. Another method would be to use some good Bitcoin Faucets like freebitco.in you can have more luck than me in 3 years and eventually Claim 200$ in Bitcoin (I Claimed 20$ worth of Bitcoin some Days ago)
