20k is the accepted price when the new event is released a week maybe more into the event the price goes down slightly to the min price that turn to be 15k
Historically, otm has a dbl plat event on Black Friday, which is about a month away. If you're going to buy plat wait a bit and double it. Chests may be best purchase, sell em or open. Imo at 15k a chest you can open them and be just as if not more profitable. If you can bet 20k or higher I'd sell. Welcome back and good luck
