In recent times I have understand that most beginner traders don't know the kind of trader they're. Either
1. Scalper
2. Day trader
3. Swing Trader
4. Position Trader.

Which of these trading methods/style is the best (that you use), and you can recommend and why.

[In this Example I will be using US dollar and Nigeria Naira]

In this Example I will be using US dollar and Nigeria Naira

       1 BTC = $13763
          X(?) = $1
           X(?) = 1/13765
               X = 0.0000727btc (sat)

Since we know that $1 give 0.0000727btc(sat). With this, it will be easy to know the value in Naira.

                      1BTC = 6400000Naira
      0.0000727btc = X(?)
                            X = 465.28Naira

This means that  0.0000727btc(sat) = 465.28Naira
                               0.0000727btc(sat)  = $1
                                                            $1 = 465.28Naira.

(Sat) means Satoshi.

Example, If trader A have 0.078btc and want to sell it to his local currency (Naira) , what's the value of his BTC worth in Naira.
Let assume that 1BTC is equal to 6400000Naira. Then
              1BTC = 6400000Naira
      0.078BTC = X(?)
                     X = 499200Naira. Therefore 0.078BTC worth 499200Naira.

When doing this calculation, you have to know (use) the current market price of 1BTC to USDT and 1BTC to Naira

The above calculation can be use to calculate any amount of BTC  to Naira and BTC to USDT, as well as knowing the value of USDT to Naira.

You can also put in the equivalent in your Local Currency to suit your need and follow the method there in.
