if i will buy 1000 dollars bitcoin at price 15000 ,how much profit i will have on 15500 dollars?How i can calculate this one?

1st) Profit is counted only when its realized. Otherwise its just called capital gain.

2) The Math
You invested :$1000
Price of BTC was : $15000
The amount of BTC you have = 1000/15000 = 0.066666667

Now when the Price rose to $15500 and you sell that.

So Amount of BTC you have (TIMES) the current price.
= 0.066* 15500 = $1033.333
You recieved 1033.33 when you sold your bitcoin.

As you can see you invested $1000 and now you have $1033.33

That means you've made profit of $33.33 or a capital gain of $33 if you didnt chose to sell it.
