There's nothing preventing you from buying $1 worth of bitcoins (say, 0.01 BTC) and tipping 0.00001 BTC each time.

I did not know you could do that, I always assumed it was full bitcoins, in that case I rescind my original answer due to ignorance.

Thanks. :)

Bitcoin would be pretty useless if you couldn't break it up into smaller pieces, especially at the current prices. =) It is divisible up to 0.00000001 (8 decimal places) and the total number that can exist is 21 million (which hasn't been reached yet).
