I will suggest you not to go for Bitcoin right now, instead of investing a small amount in Bitcoin, invest money in small market coin such as Ripal XRP which will make you able to understand the market at much less risk of investment. As soon as you are clear on the investment part and have the knowledge of the market you can enter in the Big Shark such as Ethereum, Bitcoin etc, don't be in hurry be wise in how to invest your money, after all, it's yours.
