It seems a bit unrealistic for any newbie into bitcoin to be aiming to accumulate 1 BTC unless he is already quite wealthy and/or able to lump sum and/or front load his investment, and maybe even a guy who invests $200 per week for 10 years might not be able to reach 1 BTC, since investing $200 per week for 10 years would add up to right around $104k invested into bitcoin, which may well not be enough to achieve a whole bitcoin. There are needs for newbies to be realistic with their investment targets, with maybe aiming for 1 million satoshis, then 2 million then 5 million then 10 million then 21 million.. etc. etc... and yeah of course, some folks have more resources to invest more aggressively (and/'or to front load their investment) than others.
For me, the concept of getting 1 BTC as a beginner feels totally unattainable unless of course you belong to a wealthy family. Considering BTC price, getting 1 BTC still might be beyond for newbies but it doesn't mean that they should not attempt that. It's not bad to want a whole bitcoin but I would rather achieve it little by little.
By consistently investing on a regular basis whether it's daily or weekly, I make sure that my financial position is stable. It allows me to grow my assets continuously over time. Even if I couldn't reach 1 bitcoin, I still have the certainty that my portfolio is growing thus the potential gains.
The good thing about Bitcoin is that any amount regardless of how little it is can still yield a great difference. It is important to have patience and a long-term perspective. By regularly investing, I prepare my financial security for the future.
Personally I will suggest that aiming for 1 btc is only unrealistic for every investors that doesn't have the financial ability to do so and not only limiting it to newbies coming in to Bitcoin considering the fact that there are newbies investors that may have a more reasonable size of Bitcoin compared to those that has been long in the market, since anyone can come in to the market with different levels of finance as well as strategy or strategies that suits them and in alignment with to their investment goals and objectives.
