Congratulations OP on your first Bitcoin purchase! Soon enough you will be maybe able to buy groceries at your local shop. All we need is a but more patience until this thing doesn't get going for real.

Beautiful yeah, try to spend bitcoins as much as you can in your real life. After you can just rebuy on exchange whatever you have spent. In this was you will boost Bitcoin transaction number and adoption.

I think the reasons are :

1.Bought low sell high
2.Knew the price was going to drop
3.Had enough of Bitcoins rollercoaster price and made a quick exit
4. Needed the cash
