It is problematic when folks set unachievable goals, and it tends to be better to set goals within your reach that might even be more concrete in shorter periods such as what are you going to do for the next 3-9 months in regards to your bitcoin accumulation, and where do you expect to be in 1 year, 3 years, 5 years, 8 years, 10 years etc.. The further out the projections (goals) would be more vague and you might even have base case, worse case and best case scenarios that may also project into the future... and a best case scenario for a guy to reach 5 BTC in 10 years with his current income level would have to include ways of figuring out how to increase income.. and/or other ways of earning bitcoin (which is a similar thing). and sometimes the best case scenarios are so much detached from reality that they are something like fantasy scenarios, which might not be very productive, yet they might not hurt anything as long as they are coupled with more realistic and more likely scenarios..
I have said this a few times already, it is important to set long term as well as short term goals, the short term goal should progress towards the long term ones and it needs to be realistic one too. If I want to have 1 whole bitcoin in the next 5 years then I must start investing based on it, like atleast $2000 -2500 a months will be necessary to achieve that goal if someone starts today and even with $2500 having 1 whole bitcoin at the end of 5 years is an uncertainity due to the only reason that bitcoin is constantly increasing and by that time we intent to achieve the price could have been atleast tripled so the investing amount for DCA also should be adjusted or we will fell short.
With the rapid growth of bitcoin now owning 1 whole bitcoin is almost impossible even with DCA of small amounts like in hundreds so just realize that and act according to that.
Surely $2,500 per month is $30k per year, so after 5 years that is $150k.. so it is reasonable to hope that at least 1 BTC will be accumulated in 5 years.
I have projected the 200-WMA to be right around $230k, and in 4 years it is right around $180k, so usually a consistent investing over 4 years will bring a person close to having a similar average cost per BTC as the 200-WMA... so even $2,500 per month, the odds may be against them quite reaching 1 whole BTC in 5 years, even though they might be making good progress towards such an amount of BTC in that kind of a timeline, and sure we don't know if the BTC price is going higher or lower, even though we make projections in order to help ourselves to understand how realistic some of our ideas about the future might be.
We also don't know about the ability to increase our $2,500 per month investment amount. If we are starting out with that amount and anticipating to be able to continue at that amount, then that is fine, but it might not account for everything... We also might start at $2k per month and we anticipate over the next 5 years we will be able to increase our amount to $3k per month, so we just project forward with our idea of an average of $2,500, so our actual goal might be more about maintaining an investment amount yet not exactly knowing how many BTC that will attain, even though we would like to get to 1 whole BTC in around the time frame of 5 years, so then the amount of BTC accumulated still could be a kind of tentative goal that we believe to be in the ballpark of realistic, and maybe we even consider that we might be able to accumulate anywhere between 0.65 BTC and 1.2 BTC in that timeline, and we hope to hit somewhere around 1 BTC, even though we consider it as potentially a difficult amount to achieve based on our current budget constraints and our knowledge about our future budget constraints..
