We should still be trying to be realistic, and surely someone who starts today with accumulating $250 per week of bitcoin has a chance to reach 1 BTC in 10 years if they are able to increase their weekly (or otherwise) BTC purchase amounts in the coming 10 years. If they stay at $250 per week and have no other BTC purchases, they might not reach 1 bitcoin in 10 years... So there are needs to try to be realistic within what we are currently capable of doing and what we project ourselves to be capable of in the future, even though the future remains a projection in many ways, so the shorter the period of time, we can attempt to be more realistic with what we are able to do as compared to further out projections having a lot of variables that could end up changing our abilities to buy bitcoin at the same rate or even at a changed rate (whether higher or lower).
To be realistic, we must think differently for the future, in the present time every person is being introduced to be realistic. You have certainly shown a beautiful strategy where the trend of investing for a long time can give a person good returns in his real life. If we can adopt a strategy where we are able to invest $250 in Bitcoin every week, then after 10 years our fund will accumulate a large amount of money. Although the price of Bitcoin is variable, and it is always on the rise, so if we keep $250 per week for investment for a long time of 10 years, then there is a possibility that it will be more than 1 Bitcoin. If we calculate the average according to the current market, then after ten years there will be 1 Bitcoin in the fund, and if the average price of Bitcoin is calculated as $100,000, then of course it will exceed one. Since we will invest on market fluctuations and this will be a DCA strategy, Bitcoin can be purchased at any price at any time, if the Bitcoin price is low and invested, then there will be a higher fraction of Bitcoin. And finally, if we can continue this investment for a long time, then of course we will be able to become financially independent in the future easily.
