Thank you guys for kind replies, I have choice between Malaysia, Singapore and Thai, I will choose best option for me but right now I want to go to Malaysia.
Can you suggest which city will be best option for me and if you have any suggestions feel free to give me an advise.PS: I won't be able to withdraw money from luno or local exchanges? only through localbitcoins? I don't want to trust them

Best option would be to hit our capital first, Kuala Lumpur. You'll probably need some preparation to do before heading out for an adventure ie getting supplies or most importantly paperwork with your embassy. In the capital too, you'll be able to meet someone (from each of the states) more than willing to recommend next spot for you to be at. Malaysia is relatively small anyway.
I don't think it is fair if any of us Malaysian tells you where to go in specific now.
We have 14 states and maybe about 20-25 cities and each of them has their own unique experience to offer you. Because of this, the best person to choose is you yourself.
I did some travel experiments abroad myself. From what I have experienced the only advise I can offer is - if this your 1st visit, Malaysia is moderate in every aspect.
We don't have the best tropical beach,
our culture are not the richest in the region,
we definitely are not the most economically advance country... but what we have to offer is an absolute convenience while you are around.
cheers.
Thank you, I have done some research and want to go to Kuala Lumpur at first, thanks for response
