I-bet or System bet of ABCD number is not my cup of tea.
Investment of $1,400 for 3 months and making a profit of
$930, i must say you have to be lucky, it not you might not
get back a single cent.
$1,400 divided by 3 months draw i.e.36 draws
One draw I spend $30, if i buy $20B and $10S
1st prize is $60,000, of course you have to be
very lucky, but that's possible also.
From $930 to $58,600 the different is significant.
I rather play this way.
$930 get me no where, it can't last me another 3 months.
