There are example of different people that you have said that some people have so much money because there are some people who have put some money to add to their everyday money. These are example of people and there are some people who have multiple investments and get money from other places, these are examples of such people.
Many times if someone is brand new to bitcoin and they have a lump sum that is of a considerable size (perhaps anything greater than $20k), they likely are already going to have had some practice with other investments, since it is not very common that folks are going to want keep very much money in cash, even though surely there could be some cash equivalent products that they might invest into, even bonds or interest bearing cash-like instruments.
And surely the kinds of an investments a person has and their investment experiences could affect whether and how they might get into bitcoin, and sometimes they still might want to be careful regarding how they might get out of some other investments (unless the investments are cash-like), and it is difficult to know in advance how they might want to ease out of one investment and into bitcoin, if that is how they choose to proceed.
I have seen many people who want to invest in Bitcoin but they are afraid of how they will compensate if they go into loss. Although this is a silly question and it should be because it is new people who are afraid to invest in Bitcoin. These are people who don't have money they will tell everything and those who have will mention their household expenses when they are not seen. Usury and these other things are forbidden and it is better to manage the expenses of the house by doing hard work.
Yes, if his investment is high and his variety is also high, then he must invest in bitcoin because if he spends money in it once, he has many investment varieties 10 bitcoin profit will be given. He can earn money with peace of mind and will not care about other tasks. Such people run after little money, they have no intelligence, because of which they do not have the courage to do any great work, that is why they live a middle life in the world.
These are the people who have no idea about the value of Bitcoin.
Even if they are new to bitcoin, we might not want to presume that they don't know anything about bitcoin, to the extent that their knowledge of bitcoin as compared to their knowledge of other places that they might have (or they might consider putting their value) might affect whether and if so how to get into bitcoin
If we want to understand Bitcoin anew it is our duty to understand them. If they know about Bitcoin they want to know how to trade in it then it is also our duty to explain it to them properly. Because this will give us a commission gain but the next loss will be 100k$ which is the current price of Bitcoin. So for that they start with small coin first which won't make any difference if they lose.
There are other thread in this forum where you can preach about trading I know you will never preach about the income you have lost while trading, bitcoin investment should be for a long time purpose sometimes only gives you little profit while accumulating Bitcoin and hodling for long is a future investment which will be of a great benefits for your generation to come. You won't be thinking about lost if your plan is hodl bitcoin for long, you can start accumulating Bitcoin after you have make provision for your discretionary income which is suppose to come from your leftovers after have also make provision for your basic need with the DCA strategy you can start accumulating Bitcoin gradually either weekly or monthly and hodl for long instead of putting your self into the pressure of trading/short term.
And stop misleading newbies making them believe that trading is best way to approach bitcoin investment.
