I like your dedication and ambition to gain profits by investing in Bitcoin, and let me tell you that you got nothing to worry about as you have just started and you have entered the market at not a very bad position. The price of Bitcoin is still pretty low for those who want to invest for the long term, and I believe you can hold your Bitcoins for long enough until they turn profitable.

The price of Bitcoin keeps fluctuating, so that isn't something you should be worried about. No matter how small your investment might be, it is not bad for a start, and you can always add more in the future when you can.
