Suppose you have so much money that Bitcoin transaction fees are relatively small. Don't you still have to transact a number of times proportional to the amount of money you're processing? I mean, you wouldn't buy $10million worth of BTC in one transaction unless someone were selling that much. Do the exchanges minimize the number of transactions because they process them off the books (off the blockchain) first? Anyways, it seems like these high transaction costs are a problem for everyone.
