If you want to get really technical you should bid on an increment of an auction block plus a few cents to prevent the next auction block.
If the current high bid on the auction is from $0.01 to $0.99, then the next bid must be at least $0.05 higher.
If the current high bid is $1.00 to $4.99, then the next bid must be at least $0.25 higher.
If $5.00 to $24.99, the next bid must be at least $0.50 higher.
If $25.00 to $99.99, the next bid must be at least $1.00 higher.
If $100.00 to $249.99, the next bid must be at least $2.50 higher.
If $250.00 to $499.99, the next bid must be at least $5.00 higher.
If $500.00 to $999.99, the next bid must be at least $10.00 higher.
$1,000.00 to $2,499.99, the next bid must be at least $25.00 higher.
If $2,500 to $4,999.99, the next bid must be at least $50.00 higher.
If $5,000.00 or higher, the next bid must be at least $100.00 higher.
using this you could get an advantage by say an item is 5k you bid 5100.01 and the next bid has to be 5200.01 and if someone has a snipe bid for 5200 it’ll block them from bidding.
