Cardano ADA withdrawal minimum 150 ADA at Slots.lv vs 15 ADA at BetWhale
Just noticed Slots.lv requires 150 ADA minimum for withdrawals while BetWhale only needs 15 ADA. That's a 10x difference for the same cryptocurrency.
Cardano network fees are typically 0.17-0.44 ADA, so BetWhale's 15 ADA minimum makes sense. But 150 ADA at current prices ($0.35) means you need $52.50 just to withdraw, which seems excessive.
Anyone know why some sites set such high minimums? Is it just to reduce small withdrawal frequency or are there other factors?
