Your fears are unfounded. 2 million coins were sold in the last 30 days: http://bitcoinity.org/markets/list?currency=ALL&span=30d http://bitcoinity.org/markets/list?currency=ALL&span=30d and yet the price rose from $130 to $200... So a few extra "hundreds of thousands" of coins being sold would not have been able to significantly decrease the exchange rate.
