Pretty good offer from Capital One. It's risk free, and you earn $1000 for doing very little. But you need $150,000 cash liquid to start:
First, if you have an existing Capital One savings account, you can't take advantage of this. If you only have credit cards with them (or if you have nothing with them), read on...
1) Sign up for the Capital One 360 Money Market account: http://capitalone.com/value2018 (This isn't an affiliate link, so I won't make any money from it.)
2) If you have an existing Capital One login, then sign in. Otherwise, select the option that you don't, and create one.
3) Fill out the appropriate personal info
4) When it comes time, enter VALUE2018 as your promo code
5) Deposit $150,000 of new money into the account within 10 days.
6) Leave the $150,000 there for a minimum of 10 days after that, and then withdraw most of it if you want, but make sure to keep the account open with at least something.
7) 60 days later, you should receive $1000 cash placed in the account. At that point, you can pull the remaining money out and close it.
Leaving the money there for the 60 days isn't even terrible, as it's liquid and has no fees, and you still get 2.00% APY interest while it's there.
Offer expires 12/31/18.
If you don't have $150k, no big deal. You can do the same thing with $10k, and get $200 instead of $1000.
