You can get rich by using the bitcoin as a long term investment, I think this is the best method to get rich without any big risks.
Its of course always a risk you are taking but you will need to take a minimal risk to gain money and get rich.
i think not many people want to wait a long time to become rich, especially you need a big capital for investment in bitcoin
No mate you really don't need a big capital to invest in bitcoins, you can start will a small investment, and no one is saying you to buy full bitcoin you can buy it in parts, and who knows even a small investment can give give you best returns if the price reaches the moon in future.
