In investing, there are only 3 variables to track:

A) What you have spent
B) How much token you have bought
C) The current price

Knowing these three things allows you to do something like this:

Starting an investment

Pick an investment size. I'll use $100.00, for this example.
So, A starts out as $100.00

B) is just whatever quantity of token you buy for A and the exact number isn't needed for this post. But, whatever quantity $100.00 bought would be the starting point for B.

C) is just whatever the current price is anytime you look at the market.

So, if I do a little math and say:

A / B:

Right now, that would tell me the price I just bought my tokens at, which at this stage, would be C.

This is where the fun starts...

Figure your current standing

Next week, I do B * C (How much token I have * The current price) and find out that value is $90.00 (90% of $100.00 that I originally invested). What does that mean? Well, it means that my investment is down 10%. Well, the trick to this method is any time B * C is 90% or less than my original investment value ($100.00), I spend whatever the difference is to buy more tokens. So, if I'm down to $90.00, I buy $10.00 more.

Whatever you just spent gets added to A (100.00 + 10.00) (How much I have spent)

Whatever quantity you just bought gets added to B (How much token I have)

Figure your Break Even Point (BEP)

This is pretty simple:

A / B = BEP price. If C ever gets to this price, you break even.

Note: Every time your investment drops to 90% and you buy more, your BEP gets lower.

Figure your Profit/Loss

This is a little more complicated:

(B * C) - (B * (A / B)) = Profit/Loss

That's (How much token you have * The current price) - (How much token you have * (What you have spent / How much token you have)).

You can also look at this as:

(B * C) - (B * BEP) = Profit/Loss

If it's a negative number, that's your current loss.
If it's a positive number, that's your current profit.

And honestly, that's all you need to know. Follow these steps and do not sell below your BEP and you will always make a profit.

If you are tech savvy, and understand how to create a spreadsheet to store and display these values for you, then you can buy anything, even if you already own it, and track it in the sheets as a separate subset of your token account.

If you don't get it yet, read this over and over and eventually, you will get it and be a smarter investor for understanding it.
