Why doesn't anyone seem to be doing arbitrage between KuCoin and Poloniex for Monero?

I see big spreads there, sometimes close to one percent. KuCoin has much more liquidity and far cheaper rates that Poloniex.

There's a reason I'm bringing this up. I do a lot of trading in P2P markets (Bisq, Haveno, UnstoppableSwap) between bitcoin and Monero. I don't deal with KYC exchanges, so I am stuck using Poloniex (and when I reach my unverified daily limit, TradeOgre) to settle my trades on the back end and lock in my profits. But the lack of liquidity on those exchanges is really cutting into my profit margins.

So I have a proposal. Someone who is willing to do all the KYC bullshit and document the source of funds and all that can open a verified, unlimited account on KuCoin and Poloniex. Keep Monero on Poloniex and bitcoin on Kucoin.

When I say, place a market (or limit order that will quickly be filled) buy order on KuCoin order for n number of Monero, and simultaneously, on Poloniex, place an offsetting limit sale order of Monero at 0.5% above what you paid for it on KuCoin. The combined fees on Poloniex and KuCoin should equal about 0.2%, so this would leave you with a net profit of 0.3% on every trade. Your piles of bitcoin and Monero would steadily grow. I would immediately place a market order on Poloniex and buy your Monero. Then, once the trade is completed, you withdraw your bitcoin from Poloniex and send it over to KuCoin, and then send the Monero you bought on KuCoin over to Poloniex so it will be ready for our next trade.

When KuCoin sees all the Monero withdrawals, they may freeze your account and do some AML bullshit. At that point, simply document the source of your funds and explain that you are doing arbitrage between their exchange and Poloniex.

For those of you who don't want to have to speculate on the price of Bitcoin and Monero, you could just short them (and if you don't want a bunch of capital tied up in those shorts, use leverage).

I feel that this arrangement would be ideal for people who are long-term bullish on Monero and Bitcoin and have no objections to doing KYC (and documenting the source of their funds, which I have heard KuCoin requires of anyone doing substantial Monero withdrawals). Even better for someone who could make a bot to automate this entire process, but I don't think this would be necessary at first.

Anyone who is interested, let me know. I'm looking forward to hearing from anyone interested in making their bitcoin and Monero bags grow!
