No, no, you're thinking of the $601/month thread.
Provide - ETH-BTC to a pool || Receive - aETHBTC tokens (an IOU)
Provide - aETHBTC to a pool (an IOU) || Receive - aETHBTC tokens (an IOU)
Provide - yaETHBTC to a pool (an IOU) || Receive - yyaETHBTC tokens (an IOU)
... etc.
It's interesting and affords a lot of opportunities, but you should be careful to read every contract and only enter positions that have none or little "impermanent loss". I'd recommend you find the fee structure for a pool, find the market demand and study what the pros/cons are of lending your money. You may lend out a token and it may drop in value while those IOUs become worth less while you're trying to cash them out. Or, you may borrow an asset against your assets to market sell and effectively short the borrowed token, only to be liquidated when the token rises and you need to pay back your loan. $ mv file.text !#:1:r.txt
evaluates to:
$ mv file.text file.txt
(colon separated)
!# means this command
1 is the position of the argument to be modified
r means strip extension
There's tons of history modifiers and a lot to be learned reading `man bash`.
