-> I'll only send bitcoin to sidechain if I can get some advantage e.g. fast transfer to buy coffe ( HOT wallet )
how are you gonna do this with a 1-2 day confirmation/contest period
You would do it in advance of course. Keeping a small amount of spending money on the fast chain for these sorts of purchases.
ok, fair enough. what if you need to move large #'s BTC from cold storage into scBTC quickly if it becomes clear the SC is going to dominate b/c of some innovative feature and the exchange price is fluctuating wildly in the meantime?
