I'm no currency expert but as with almost all fields this isn't a case of learn on the job. You'll definitely gain a lot of experience but if you play with real money without much direction or knowledge, you'd be forced to close up shop pretty quickly. In other words, you'll be bled dry.
My advice is to try and learn the basics behind supply/demand, inflation, speculation and currency. Make sure you are up to date with current affairs. You need to be ahead of the game, both in terms of global politics and economics.
Read up on FX trading and buy yourself a good laptop and a fast internet connection.
Do as much research as you can. Try pray icing by using a dummy trading account (where you play with fake money). Once you're more familiar with it then take the plunge
Oh, i have lots of experience trading FX, I manage an investment fund so yeah.
I was thinking more of a cash to Bitcoin and Bitcoin to cash exchange rather than a Bitcoin/Fiat/Altcoin exchange.
I think I could do it manually so the process won't be hard for the start, but knowing where to get a supply of money like from Neteller or Skrill or Paypal would help..
I only really have Bitcoin and Cash at hand most of the time
You should always have liquidity If you want to have customers and I guess that processing the transaction manually could make you loose some costumers because they want fast transactions and there will be definitely the trust issues that comes with it . If we assume that you won't have much users when you start then I guess you should have at least 25 BTC to start with.
It also won't be easy to find suppliers for the payment methods you are looking for, I guess you should get the BTC and make a bitcoin debit card and deposit using it into both Skrill and Neteller and then sell from there with a higher fees. Finding suppliers from the currency exchange section is not really an option as the fees are high and you will end up losing money instead of making profits.
Yeah you're right. I should probably need about 25 BTC if I were in the US, however in the Philippines I'm sure around 5-10 BTC on hand would work fine since 1 BTC is 45k PhP which is pretty much max in AML laws in the Philippines
