RCG Markets has a flat minimum deposit of 50 Rand across all their account types.
Both the account types with bonus and the ones without bonus, have the same minimum deposit of 50 Rand.
But there is a catch; the RCG accounts without bonus have higher leverage up to 1:2000 while the accounts with bonus have lower leverage pegged at 1:500 maximum.
