Investing is not an option to increase your bitcoin because there is no way you find a reliable place to invest your bitcoin. All programs who promises to give daily profits on your invested amount will eventually run away with your money before your get your investment back. So never look for a place for investment. Till date I have not found one.

However, trading is a highly recommended method to get more and more bitcoin from your efforts. Trading has the ability to give you a huge profit if you can play it right. If you don't know what trading it, go to youtube and you will get a lot of videos which will explain trading in details. Start with a small amount and once you are comfortable with trading, increase the amount.
