There are 52 weeks in a year.. not 48.
It surely would take a long time for a person with $10 per week to build a decently sized bitcoin stash.. but surely investors can ONLY do as much as they can do, and surly if they are able to hang onto their investment and make sure that they don't lose it, then even smaller amounts of investment into bitcoin will be better than not having had invested in bitcoin.
This is true, consistently investing even i small amounts can lead to good accumulation over time. Whats more important is that they are dedicated and consistent to their investment. In real life there are people who couldn't make a big purchase at once, for example buying houses, starting a business. They started with the little they have gradually till they they achieve those big things. Same thing can be done in Bitcoin investment It might not seem like much at first, but over years it can add ups to a substantial sum.
This points us to the direction of encouraging regular investment. It helps smooth out the impact of market fluctuations which is a huge limitation to people who barely started their investment. One key note we should keep is that investing is like a marathon and not a sprint. Being focus in it and staying patient helps in our long term goals and its better to rely on it than getting caught up in short term market fluctuation.
