Per E-TRADE: Market value of account cannot go below $50,000 original investment "ever" during first 6 months.
The way to handle this is to keep it in an interest-bearing account for the first six months, like a money market or government bonds, etc.
There are no required trades. Just opening the account and maintaining the $50,000 for 6 months guarantees the miles are yours. SO I'M IN !!!!!
Not vouching for being able to get the miles from E-TRADE though. After my experience, I will post how long it took, trouble, etc.
Have a good one everybody.
