I'm able to buy btc for bitstamp minus 2 percent locally in Toronto. How can I make a decent income by selling btc?
Sell it Bitstamp +5% at Localbitcoins using non-reversible payment methods (western union, moneygram, cash deposits in your bank, etc...)
This, except sell for bitstamp +20%, you make a lot more money that way.
Don't undercut the competition too hard, it hurts everyone.
You will have to learn everything else on your own but this is the way to do it.
Agreed. Localbitcoins is the way to go. Best payment method to accept would probably be a bank transfer. No chargeback and funds appear fast.
