For me, investing in bitcoin is not so expensive. How do I say so? Because I don't invest or buy the whole coin. I can buy and hodl little by little when I have extra (which I can afford to lose as we all know that bitcoin is volatile). If you want to start investing in bitcoin, you start small and make a goal. By starting small, you can learn how does bitcoin works until you know the strategies you should use. Whether it is $10 or $10,000 as long I know I have bitcoin or I am still part of the network, I always see the brightest side and see its potential growth.
