Any opinions on Monero's blockchain size?  I mean ... there's already a 1.7GB blockchain size.  In 3 months it's half as large as the litecoin blockchain - so when it's litecoin's age if adoption doesn't increase any we'll be seeing 17GB since litecoin has been around 10X as long? 

If adoption increases by 4X - 5X to knock litecoin off as #2 - we'll see a 68 - 85GB blockchain in a few years?

FWIW - I've got no horse in the anon race.  Darkcoin is a borderline scam IMO.  An XCurrency dev did a massive pump pump job on cachecoin & appears to be dropping his ASIC project for LTC so I'm avoiding that like the plague.  Just not seeing a clear winner in anon ATM
