How massive will be exactly the increase in supply? I didn't follow the latest developments, no mention of this increase on OP, but I own some SIA and I'm interested in these marginal details like increment of supply...
There will be no increase in supply. The supply stays the same. The network's hashrate on the other hand will increase drasctically, so the only ones who suffer are GPU-boys. Well I have news for you: GPU mining is over. Invest in new equipment or you'll be out of the market in a few months.
Increased difficulty drives the price up. It's going up already as we speak. Look at what happened to other coins after Bitmain released their ASICs:
LTC - x30 in 1 year
DASH - x70 in 1 year
So just buy more SIA and enjoy the ride.
That's right! I bought this coin at 0.03 next at 0.07 and last time at 0.04. I think it have a great team, working technology that regularly updated and good growth potential in 2018!
