sell to me lo

I noticed different exchanges has different pricing for each cryptocurrency. Some are cheaper than the others and vice versa. Is it because of the supply-demand in each exchange? Cuz I was wondering, if let's say I buy 1 ETH at USD180 at Exchange A and then transfer 1ETH to Exchange B, then sell it at USD190, instant USD5 gain on top of whatever profit I make?       

And some people actually do that.
It's called arbitrage.

Sign up with all of them if you're serious about doing this.

How hard is it to an exhange? Hmm

How hard is it to start an exchange was what i wanted to say loll

There are various sites for MYR/BTC exchange Luno; XbitAsia; Localbitcoin
If you want to use credit card, maybe try Cex.io, some bros here mentioned that it is cheaper this way.

same, been using xbitasia for sometime. like their withdrawal. they will email you follow by CIMB's email. the spread swings 2 ways, sometimes its cheaper than international price, sometimes its higher than international price like now. to me its simply a supply and demand of btc in malaysia, if no many ppl selling btc in malaysia... then the price of BTC in malaysia is higher than the international price. crytpo is not like gold or forex, the diff btw countries and platform is small.... even polo value is different from bitrek. im considering to move out my btc from polo because rthe lending rate sux. not even 0.1% a day.

Why do you want risk your BTC getting stuck in the chain for transferring twice instead of once straight to the destination ?

you are buying 0.1 unit of ETH at USD18/ETH. the current price is USD183/ETH. barring any major crash, you won't be able to buy it from other sellers at trading.

Convert to BTC and sell it off on localbitcoins or xbitasia lah.

try https://coinbox.biz/cblialn.  There is a Rm30k buy wall at RM 10k per bitcoin.

By then your ether would have went to the moon and you'd be driving lambos (lamboS, not a lambo).

Wait for this: https://localethereum.com/

Why i cannot see that??

Anyway, it will uses best price for both sell//buy, like KLSE, right

Open an account in the exchange and get the deposit address. Then send to the exchange address directly from wherever you buy. One transaction.
Check the transaction fee with the seller to avoid it got stuck in limbo

Please tell me that you did not put wrong buying rate

0.09070 = 200+ USD similar to ~0.9 ETH. You've got 0.15
