There are no block reward issued coins on a 1:1 sidechain, only coins that are locked by their owners in that chain.
it doesn't have to be that way.
which is precisely why SC's are a prelude to a shit fest with all sorts of blossoming SC's even worse than the altcoin explosion.
I know!
But to be honest I couldn't care less about this. Scammers will scam and speculators, suckers and fools will lose money. Sidechain doesn't enable them. In reality it confronts them with the question I have presented before : now that 1:1 sidechains exist, what is so special about the features you are proposing that they need their own coin to function, because the guy next door is doing just the same thing BUT on a 1:1 peg.
If they answer me like smooth believe they will : "because I want it to be so". Then F*** them, I'll buy from your neighbour at the 1:1 shop, there's MUCH less risk.
I also feel it's wrong to say SC don't enable scammerers it does it on a whole new level. I also feel your use of the word buy implies a one way exchange in value not a risk free leveraged of one's Bitcoin.
