think some miner is going to reorg the bch chain to steal them a $500 goft card??
Indeed, the required security should be relative to the value they want secured. But that makes things more complex.
yeah, they should really be more clever and make it proportional to the amount
No, it makes sense to want confirmations for higher amts, b/c double spend is possible, but expensive when there's no confirmations. Each successive confirmation makes a double spend exponentially more expensive to manufacture.
After 1 conf, a double spend is impossible. A chain reorg is what would steal.
My bad if I got semantics wrong. Both are "attacks"
