It's difficult to see any real world use for SIA due to the availability of cheap / free large storage resources. I would put money into SONM instead which is a decentralised super computer. Works like SIA but instead of storage it will use your processing power instead
I would also put money in SONM which is a new and good project like Sia, I see this as a very good also brave move, but still I wish there was another option except fork.
