Hopefully I'm tracking the question but the market price for bitcoin is always set to the present. If you bought bitcoin at different points in time, it will always trade at the current market price regardless what you may have paid for them at a certain point in time.
Also there are no blocks that you acquire when you buy bitcoin. Bitcoin is just a giant ledger that keeps track of how many transactions different addresses possess. Your balance is the total sum of all the transactions you've received. The 'blocks' are part of the actual bitcoin blockchain that verifies the latest transaction activity on the ledger.
