user83355: Scenario 1:
I bought k bitcoins at unit rate X in the past, with amount A. If I want to sell them now, I look at three unit prices:

Buy Price
Sell Price
Spot Price

Question # 1: At which price I will be selling the k bitcoins that I have?

Scenario 2:
I have A dollars with me and I want to buy bitcoins with it. I am looking at 3 unit prices:

Buy Price
Sell Price
Spot Price

Question # 2: At which of these unit prices I will be buying the bitcoins?

For the sake of understanding, lets say I am using either Coinbase or GDAX
List item
to buy/sell in both above scenarios.
Thanks

user75001: Scenario 1
Using a simpler example, if you visit bitcoin.com.au to sell Bitcoin you will get the sell price for k Bitcoins. In this example, it is a spot sell price.
Scenario 2
Using a simpler example, if you visit bitcoin.com.au to buy Bitcoin you will pay the buy price for k Bitcoins. In this example, it is a spot buy price.
Elsewhere
On market exchanges, the buy and sell price are market indicators. These are the general level of the buy and sell orders. You can creae a buy or sell order for, usually, any price you like but the indicators show current trade values.
If the exchange lists a spot price, this is usually their spot buy price, for if you wish to sell to the exchange directly without creating a market order and waiting.
