make security deposit based on amount. #985

For small trades 15% is fine but if I'm trying to send $8k in cash in mail for xmr, I shouldn't need $1,200 in monero just as security deposit, I'm not going to do it, maybe lower to 10% or 5% based on amounts.

Yeah it prevents spam but it's a bigger more problematic issue for real people

The decentralized nature of Haveno creates additional risks. Suppose that there was a flaw in the trade protocol which would allow a taker with a modified client to force the creation of an invalid multisig wallet which would lock up both parties' funds forever, and the minimum deposit amount was only 5% for sufficiently large trades. Someone could troll you for 20 XMR at a cost of only 1 XMR themselves, and with sufficient funds they could hit the entire network at once before trading was shut down and the bug fixed.

It also wouldn't work with 2/2 multisig like Bisq now uses, for the same reason.

The prospect of the counterparty accidently losing access to their keys (on a large trade) is one argument against moving to 2/2. 2/2 presumes that both parties act rationally, but bugs & data loss aren't rational.

I believe this is being answered with the proposal in issue #999 which will basically be 2:2 multisig trade without the help of arbitators. ie. Trade at your own risk there will be no assistance if you get scammed as you had option to trade 2:3 with minimum security deposit of 15%.
