Common perception of Square is that it's unlikely they'll be able to live up to original expectations. Jack Dorsey is no more the next Steve Jobs than Grant Hill was the next Michael Jordan.[1] That being said, if people are still willing to give them tons a cash it gives them the ammunition to make another go at their Moon Shoot, by all means take the money.

So probably a good move for Square, and probably not the wisest use of cash for the investors. That being said, it's tough to find a good home for cash these days thanks to global QE.

As for me, given the choice between putting money in the 10Y notes at 2.6% (pretty close to inflation over the last 30 years), Square, SP500 fund (19.69 PE or 5.1% yield) or putting it under you mattress, I'd opt for some mix of the mattress and SP500 index fund.
