Not that I'm big fan of speaking about this thing at all but people that comes from Duel Arena aren't usually very pleasant and acceptable to talk with.
So main idea of this is that staking amount both cash and items(depending on G.E. value or perhaps high alch value for some items, etc. like adamant ones which in G.E. price checker is 1M~ for unknown(to me at least) reason) accordingly will go up with total level. What does it mean? If you were to have, let's say, a total level of 750, your highest amount of coins or items value is no more than 7,5M and so on. When you get maxed(2277 total as of right now), your amount increases immensely, therefore you can stake all-in, meaning unlimited with max stats.
Just for the record, stakers don't level up any other skills so if they were to stake some more items/cash they need to do some skilling for it to gain. It benefits both economy and stakers in a way where economy will get alive again and stakers won't lose items instantly they gain more than their bank was(etc. decreasing flaming or any other way of bullying coming from stakers as they rebuilding goes usually like this - goes stakes all-in, loses, then goes to G.E., begs for more cash goes to even more staking.)
I don't intend to get positive replies on this suggestion as this might have some minuses of its own but overall I'm looking forward to anything players could say that could be to it, feedback is always welcomed.
Implementing this I'm also aware it might take some time so no need to hurry
