I see your suggestion is good. people who start investing in Bitcoin with small capital will only get small profits too, conversely, those who invest with large capital will get big profits too, but you don't explain that Bitcoin won't make someone rich in 1 night. btw, I'm already wary of giving advice to people who only invest small money in bitcoin, most of them hope to make 1 million dollars by just buying $50 worth of bitcoin LOL
I have believed every one having his own view and mindset because for me still investing $30 in bitcoin is good because if we keep going with our predictions and have sometime for checking charts this can go better in few months with the view of bitcoin nature is unpredictable but if someone wants to invest for long time this is still good idea even it's not making him rich but still can give better profit which can solve his issues and also can help in real life for many other problems as well.
Bitcoin is future no one having doubt about this all with the latest updates and technology things looking much better and surely these small investments will also have worth for investors but still I will recommend if someone wants to investment he needs to read all plus and negative points of bitcoin and its investments as well.
