I am still trying accumulate $20 Bitcoin in daily day trough price under $30,000, my planning until Bitcoin raise to $50,000 stop accumulate and take profit since one years spent few percent of my salary spending to invest in Bitcoin. In my environment have tradition with saving money called lottery club or "arisan" and each time of duration have more than 20 until 30 member, each member will get their fund in next ten days later which spending from 10$ until $20 in daily day and take more than one or two years duration for every one getting their saving fund. But I change my mindset than holding with fiat get potential inflation in the future, I try with accumulate Bitcoin and not stopping yet until bitcoin one day later back up above $50,000.
Its bitcoin still on the dip and as much possible accumulate and keep holding until one time selling our Bitcoin assets in the higher price,
It's too big and I don't think it will be able to be consistent for a long period of time.
Even if it's good but if it can't be consistent I think this can actually hinder. I'm not saying it's not your method, but this level of aggression will be difficult to balance if you have a normal monthly financial situation.
$20/day = $140 per week and for a month for example in one month 30 days = $600 I think this kind of money is difficult to get with income in some countries with lower salary levels.
Maybe it can happen for you but I just want to suggest try to reduce your aggressiveness a little bit because it's not just about 1 or 2 months but consistency needs to be maintained more than that.
I think this is related to the income we have, of course everyone has different abilities, including in this investment. Again, planning is the most important thing, it doesn't matter how much we are able to invest in every day, every week or every month, as long as it doesn't become a burden for us in the end. I mean if we have that ability (investing $20 a day) like the OP did then do it, as long as that amount is not forced, or in other words we force ourselves so that the amount must always be there every day, it is not wise or even tends to be bad.
Different opinions will always exist, and again it may be based on our capabilities.
Talking about the amount of investment, it really comes back to each individual because he will do it according to his abilities, indeed the monthly amount is quite large and the average standard salary in several countries is indeed not enough for that, but if he has a good position in his job, he will definitely able to do it.
In my view, collecting bitcoins at a total price of $ 20 / day is of course an inappropriate strategy in my opinion, because it will take a lot of transaction fees which are quite hefty if collected, it is better to extend the purchase interval, for example once every 2 weeks or once a month with a total amount the same one.
For example $ 20 X 14 days (two weeks break) = $ 280, and he only makes 2 transactions to make purchases in one month, in my opinion this method is more effective and economical for buying bitcoin.
