Fiat exchanges are how most people make their entry into cryptocurrency exchanges. The UI is appealing and rather easy to use as a beginner. Sadly, victims are often the fiercest defenders of such scams, at least until they lose their shirts. Day trading is based on technical analysis; the ability to make market decisions based primarily on price charts. Prefer those exchanges which offer proof of reserves for client Bitcoins, regular external audits for client fiat funds and have a long history of secure, ethical operation.
