What's stopping you from buying a smaller portion of a Bitcoin? You can buy a fraction of a Bitcoin, you know....
You`re right! I have it stuck in my mind`s eye that I ought to have either a full `coin` (1 BTC) or nothing. I`m gonna go ahead buy a teeny slice of BTC (an amount I can afford to lose, should that happen), just so I can dabble, learn, and have fun with it.
