Hi I recently purchased my first amount of Lindens. I paid $44 (which I know includes tax and fees) and I received L$ 9840. But when I looked on the recent exchange rates it says L$ 10000 should be $ 31.25. Even with adding tax and fees surely the L$ 9840 I purchased shouldn't come to the $44 I paid? In fact, if the website I used for exchange rates is correct then for that amount of Lindens it should be $ 30.75, then a bit more for tax and fees. This is the website I used: https://ld.currencyrate.today/ Is this the wrong website to use? Is there a site that gives me the correct exchange rate so I know before I buy? I'm just trying to work out how much money it will cost me to rent land each month when I know the amount in Lindens. Thank you Franz
