Yes. Even higher if uplift and put new placement everyday. But who so rajin. 
Been there, done that (>RM5k)
My 4 digit is peanut compare to someguy with 6 figure 

mother of gawd... why i late know this

Oh yeah, write a 100k cheque with RM 0 in account, walks away with 100k cash and let the cheque bounce.
Why I never thought of this? 

but the thing is, does the bank even allows it in the first place?

Is not a crime. You can write a cheque but say your bank account is zero = cheque bounce.

what is the point for this? a bounce cheque will get penalty for some amount....
this is like after eating, got nothing to do 

WHAT HAPPENS WHEN YOU
ISSUE “BAD” CHEQUES?
Each “bad” cheque issued is treated as
one “bad” cheque incident. A warning
letter from the drawee bank will be issued
for each “bad” cheque incident.
If three “bad” cheque incidents are
committed on the same account over a
12-month period, you will be deemed as
a “bad” cheque offender and as a result:
• The current account you are holding will
be closed and your name will be reported
to the Credit Bureau by the drawee bank.

dont discuss publicly anything illegal or circumventing laws/policies

No la, what I actually meant was, let say u have a large fund in Citibank. And you want to place that amount in e-GIA. If you write a Citibank cheque and deposit it into your MBB acc, it would take 2 days before the fund is available for u to place it. You are gonna lose 2 days of interest. Now assume u straight away open a GIA with that cheque over the counter. Is that possible? If yes, then the next question is for the GIA you place over the counter, can you do the upliftment via M2U?

Placement over the counter for GIA is definitely possible if you read the T&C:
http://www.maybank2u.com.my/WebBank/gia141016_tnc.pdf

"GIA campaign placements can be made over the counter (OTC) or via online platforms i.e. web or
M2u application. It is compulsory for customers to have either Deposit or investment account with
Maybank for profit payments"

The question is can you do placement by cheque? I have done that before for FD, cheque from other banks.

Nope. RM1000 x number of days/366 x 0.0355
