Why look for large gaps in price which can result in risk dealing with strangers?
Instead, create account on major exchanges, look for smaller profit, then just rinse and repeat.

I don`t like rolling lots of money through unknown and sometime illiquid exchanges. Most of the times it is very easy to get the money in. Problems mostly start when trying to whithdraw. Also I like +10% premium because when trading for small % the risk is very high because of volatility and transaction times. As I am not a full time trader and have other things that occupy my attention I prefer building real human relationships and doing bigger transaction and be safe volatilitywise. Of course there is always a risk when dealing with other people and sharing profit margin. But there are security steps like escrow or alternating day by day who sends first. It is still worth the risk if you can participate on the big +30% premiums like the korean markets. I will definetly give your approach a try. If anyone has a experience to share involving another human arbitragin feel free to chime in.
i honestly don't know where you find your 10% 30% deals
Japanese, korean, australian exchanges do not sell at such a big difference, and the gaps are shrinking day after day
best crypto to fiat deal you can find as of today is perhaps 5% after fees
