Coinhako

This is kind of different exchange, rather an OTC outlet. You get a fixed price, that is closely following the market.

Yes, market, Coinmarketcap it is. If you take the US$ price and convert it to S$, you're spot on.

Not bad, but you need to act in real time, there is no limit you can set, you need to buy or sell at market price.

Which is what makes it different. Competitive prices, you could also deal at Gemini for instance but then you first need to send (and convert) your S$ funds to US$.

Small exchange, I like it.
