Re: what is the best exchange trading i can trade with

[ironic mode = ON] I suggest you, C-CEX.com very professional team [ironic mode = OFF]

thanks i'll check, but do you try it, withdrew is ok?

He was being sarcastic in other words he was joking. Use C-Cex at your own risk, read more about them in scam accusations, just use the search bar and type any exchange's name, you'd find what all scammy shit they have done.
You want to deposit fiat and buy bitcoin, use localbitcoins.com , they are the best when it comes to security of funds when you buy fiat, then you transfer your bitcoin to any other exchange and trade or whatever, and for selling you do the exact opposite. If the fee is high don't get disappointed, it's worth for what you're getting.

Thanks a lot for this information.
I hope your advice people as i am new.

I'm a big fan of localbitcoins as well.

Since you want to deal with fiat as well, I would say localbitcoins is one of the best. Even though they're not actually processing the fiat withdrawals itself, it is often much safer to deal on localbitcoins because localbitcoins is simply a third party acting as escrow. Sites can have problems with withdrawals all the time, and it may delay your withdrawal as a result. You'll have near instant exchanges on localbitcoins, and bitcoin withdrawal fees are only 0.00015 BTC right now.

Best of all, support is the best i've seen on any exchange platform.

I'd recommend it to you without a doubt.
