Blockfi is a Crypto Exchange Platform just like Celcius. For this bonus you need to deposit $100 and keep it in there for at least one month. Usually you will get the bonus after the 2nd friday of the month. Once your bonus is there, you can withdraw the money.
What do you have to do exactly?
-Apply through my ref link or just use the ref code: a43689c7
https://blockfi.com?ref=a43689c7
-Do a KYC (Know your customer, so they know your identity) On Blockfi this is quite fast
-Deposit $100 in fiat or send Litecoin (cheapest, otherwise you have expensive Eth fees)
-Leave your $100 for at least a month
-On the 2nd friday one month after you deposited, you get the bonus. This also works for referring people. So if 3 of your friends joined through your link you get 4 x $40 = $160 dollars
After all this it is important to know that you get 1 withdrawal for free every month. So a 2nd one would cost money. Just double check if your withdrawal is correct!
