How much cash do I need to run a crypto exchange. Coinbase has gotten multiples of 100s millions in FIAT VC funding. So they can cover withdraws.
But what if you are a small startup ( maybe ICO ) who wants to provide exchange services. If lots of people start withdrawing FIAT from you ... you can't keep up, unless you are taking as much FIAT deposits as they are being withdrawn ... any thoughts ?
If you are running a pure exchange, you just need capital to cover your set up costs and day to day operations, if you are not earning much. You don't have to worry about fiat withdrawals, because they are matched against buyers orders. So only when people deposit fiat and buy bitcoins, will the sellers get fiat to withdraw.
