Limit buy question.

New limit buy lindex is wonderfull but has a "small" problem.

the difference between "limit buy" and "limit sell" best rates are just a little above of the 3.5 % LL fee to make profit. "limit buy" are being used by daily traders to make small profit. This is not wrong maybe.
But;

let me explain with an example:

best sell rate: 320
best buy rate: 340

then a guy is buying 350000L$ at 340/usd for $1000.

then selling this 350000L$ at 321/usd. to fast sell, so he/she can buy L$ again to sell.
And he/she is getting 1050usd for this sell and buying again 350000L$ at 341/usd. because traders see the rate is at 321/usd then pulling the best buy rate to 341/usd. to make profit again.

This will continue, and L$ will loose value daily 5-6 points.

This is not a big problem for me actually because in my opiinion because of the lack of supply/sink balance at economy L$ will lose value in one way or another, this is only making it faster.

My question is; do you see such daily L$ traders as a problem for the economy and will take necessary actions for it or not?

Asking about this...
