I'm sure you're thinking of a 10% return in 2 years, not 110%.  Except that 10% in 2 years is absolutely exceptional.

Most mutual funds managed by The Vanguard Group have a 10% return in 5 years.  This is some serious money in some of the hottest growth sectors, coupled with a couple of advertising tricks common to mutual funds that artificially inflate the return statistics.

Let's take my main Pyramining account into consideration here...  http://pyramining.com/account/browse?id=6nak28t7

I've got an average completion of 3% on 1.53btc.

The day I joined, July 21st, 2013, the price was $85/btc at coindesk.

Assuming (incorrectly) that I deposited all of my bitcoins on that day, that means that I would have paid ~$130.

Today, that 1.53btc is worth ~$482.

That is a 370% increase in value over one and a half years.

However, since I deposited my money into Pyramining, this means that I have $15.75 available, from the 0.05btc that I've been paid.  (Don't worry, I re-invest it into another Pyramining account further up the chain. I'm not foolish.)

That means that over a year and a half, I've gotten 12% ROI.

That is exactly in line with the top performing mutual funds at the top performing mutual fund company... without the bullshit tricks that mutual fund managers use to make their funds looks more profitable in retrospect.

I can expect 100% ROI in 10 years, a whole 10 years shorter than billionaires typically expect their 100% ROI.
