Just confirming with token lock up, that when you buy from an exchange (say, Binance since that is who you have the strongest partnership with) that you only need to buy the EXACT number of MCO for a particular card?

So if I were to buy 50 MCO tokens in preparation for getting a Ruby Card, and I got these tokens from Binance, there wouldn't be a withdrawal fee from Binance to the MCO wallet that would mean I'd have slightly less than 50 MCO tokens in the end, so would be short of the Ruby Card? Also same question for the other cards like 500 MCO card.
