The truth about this Bitcoin investment matter be be say, the amount wey I dey use no dy consistent because some week end, I go use #20k which is almost $15, while some times wey the week stew for me, I dy use #30k upward or more, and even some weeks, I no dy invest anything at all because the charging of phone business wey I dy do, dey very lucrative only when nepa seize light.
So what I dy talk all this is that, investment should be done base on your own financial capabilities and reality, because no where Dem write am say you must use this or that amount use invest in Bitcoin, you invest base on your discretionary income available at that particular time.
Your illustration here is a good one and serves as a guide by stating in details how much goes into your weekly and monthly Bitcoin investment.
This is because most of our illustrated investment pattern may seem abstract to some beginners who dose not know that with 20k one can actually segment weekly or monthly Bitcoin investment.
I believe success in any investment begin with having a working knowledge to be able to operate at your level of financial capacity per time.
