In 2013 January, you would have been able to purchase
BTC2.5 with $25
In 2011 January, you would have been able to purchase
BTC100 with $25
In 2010 January, you would have been able to purchase
BTC2,500 with $25
Imagine the returns, had you invested $25 either in 2010 or 2011.

Too bad that we are not on that year anymore and not all the people will take the risk to invest to bitcoin way back then.
But upon seeing that opportunity, I feel regret that I didn't invested to bitcoin way back when it was still kind of low price.
And right now the only thing that you can with this amount is with trading and the profit is unstable and unpredictable
