why do some crypto withdrawals take 2 seconds and others take 2 hours lol

Ok so i've been playing at a few different places lately and the difference in withdrawal times is honestly wild. hit a decent run on crash games at BC.Game last week, cashed out like 0.08 ETH and it was in my wallet before i even finished closing the tab. no joke maybe 30 seconds. that's the standard i expect now tbh

then i tried Roobet for the first time and my BTC withdrawal sat "pending" for almost 3 hours?? same amount roughly, same wallet. i wasn't panicking but it was annoying. support said it was a "manual review" which... ok fine but warn me about that upfront

i think the difference comes down to whether they have automated vs manual payouts. BC.Game seems fully automated, Roobet might do spot checks. if you're deciding between them there's a decent breakdown at bc-game that covers the withdrawal stuff too

anyone else notice this pattern? like which casinos have you found are consistently instant? curious if duelbits or stake are any faster cause i might switch my main spot </s>
