You do not need to have millions before you can invest. Just like what savings is to a regular fiat bank, that's what HODLing is to BTC investment.
This is a good plan actually. Here the risk intake is also less and perfect for the beginners. If you are a beginner your first motive should be to not make losses, rather than making profits. If you master the art of minimising the risk, then automatically in the later part of time you will make profit. But as a newbie your sole motive should be to learn and see how market fluctuates. Holding Bitcoins with some good amount of money can be the best thing.
