Moreover, I had to wait when they all be counted by BM + wait for tokpie checking and depositing.
Tokpie checking and depositing was very quick from my memory.
You say 10-15% for borrowing. But you don't have to borrow. It's easier just to buy.
Only if you have the money. Quick example: translation stake cost 122$, if a hunter want to deposit his 28 weeks worth of stakes he'd have to collateralize 28*2*122*3=20 496$ what kind of bunty hunter has this kind of money to spare

?
Actually, new bounty stakes depositing is better... it allows to earn more than before.
Only if you have enough money to begin with.
High competition under previous scheme made stakes prices very low (you probably forget it)
No, the price of stakes depends mainly on the project and not if there is a lot of bounty hunters trading the stakes or not.
Tokpie checking and depositing was very quick from my memory.
During big campaigns (like youengine) when there were many deposit requests it could take days
Only if you have the money. Quick example: translation stake cost 122$, if a hunter want to deposit his 28 weeks worth of stakes he'd have to collateralize 28*2*122*3=20 496$ what kind of bunty hunter has this kind of money to spare

you will get the same percent of profit if deposit 0.28 stakes. It will require just $4.9 as collateral. I like that most of hunters so stupid - many of them don't understand that they can deposit even 0.01 stake get TKP, and repeat again-))
Only if you have enough money to begin with.
I show you above that this is not necessary to have big money. If you have $5 or $500 the return on collateral amount will be the same (in percentage)
But if you have more TKP it will allow to earn more. Simple math.
