If poor people can invest a few dollars a week, they can make a big investment in a year. If poor people invest a little, they will eventually become rich. They can enjoy many things in life. If they invest in Bitcoin along with other income, they will eventually reach a good level. If they invest in Bitcoin, they will see other income levels. However, it becomes difficult for poor people to do all this.
No, I think that this is misleading, investment in bitcoin in a year especially when you are a low coiner wouldn't do anything significant on your finance just in a year.
For a low coiner or the average income earners that want to be successful in his investment, and be rich as you called it, he need to accumulate Bitcoin gradually and consistently through the dca accumulating strategy weekly or monthly for the minimum of ten solid years, by then he might have accumulated a very good stash of bitcoin that can turn his financial status to the better, but anything short of that is actually not long term, and he cant make anything significant with that especially if he is not consistent.
So what am trying to say is that the stash of bitcoin you can accumulate is what's going to determine if you are going to be successful/rich or not, you can't just invest only $100 and be expecting to harvest $1M in a year as you think or even 10 year time.
The level of your Bitcoin capital plus returns on investment (ROI) depends on your stash, you can't hodl a few sats and expect to be rich in 1 year or 10 years. Poor people or low income earners that are determined to invest in Bitcoin on the long term should have a strategy to keep them focused and there's none better than DCA method. If they are able to scrap out discretionary funds from their income and allocate some of it to buying Bitcoin then they can buy and continue buying into the future.
Although my best advice for poor people that wants to enter Bitcoin investment for the long term is that they need to understand financial management. If you're poor that your income cannot cover your basic expenses there's no need to force yourself into Bitcoin investment because you'd end up selling prematurely to take care of your basic needs. This will make you to deviate from DCA method because it'll defeat your goal of long term hodl. Make sure you have a functional discretionary funds before getting into DCA method.
