I think it doesn't mean that whenever you're going to buy ciggarette, you instead buy bitcoin that is such a low cost. I think your term is that you save your money in buying bitcoin so that in the future you will have enough savings in order to buy bitcoin and then hold it. That decision is indeed a good and very wise choice. A lot of person today doesn't care about long term plans but for only their short term plans. They are contended to what they have today or at the very specific situation yet they don't think about the future. That decision is a very common but very helpful idea in order for the future to be ready. Instead of going to your vices, jsut save up for your future preferences and use. Good Job!
