I don't have as much knowledge about investing as a professional investor but if I have knowledge I can invest in Bitcoin and if I have the patience to hold that investment for a long time I have gained patience and knowledge about investing. I am just waiting to invest maybe soon I will fulfill my investment dream by investing in Bitcoin. The amount of money I want to invest in Bitcoin may not be much but this is the beginning of my investment.
That's a very nice plan buddy, perhaps while you wait to get ready for Bitcoin investment you could utilize the opportunity by learning the basis and the concept of Bitcoin, and also knowing the investment risk and ways to avert it by managing the risk, however you are in the right place because all the knowledge and strategy of accumulating Bitcoin is always discuss here, so it will help to enhance your knowledge about Bitcoin before you will even start investing.
Perhaps I would like to correct an impression you said "the amount of money you have may not be enough", it doesn't work that way in times of investing on Bitcoin because Bitcoin is not like stock investment that only allows huge amount to invest but on the contrary Bitcoin allows you to invest as little as you could afford.
However that's why DCA strategy came to our discussion because it will help and guide you to regularly accumulate Bitcoin with small money you have, and within years you will be surprise to see the amount of Bitcoin you most have accumulated on your portfolio.
