hi there, is there a wallet like bitensure that gives users interest when they deposit funds?
or are there any altcoins alike?
Out of the major exchanges, Bter used to offer interest for deposits. You had to log in once per day to claim it though. Not sure if they still offer this anymore after their major hack which happened earlier this year.
As for altcoins, there is an altcoin called BitShares which has market-pegged assets. They're not actually backed by the asset that they represent but instead, they use a complicated mechanism to keep their prices reasonably close. It has worked pretty well so far. One of these assets is bitBTC. There are a few others such as bitUSD and bitGOLD. These can earn interest while reducing the risk of being goxed since the assets aren't kept on a centralize exchange:
"If you own BitBTC you can earn dividends on your bitcoins," said Larimer. "If you have a thousand bitcoins and you convert them to BitBTC, and then you hold it for six months, then you convert the BitBTC plus the dividends you received back to bitcoins, you’ll end up with more bitcoins than you started with."
You can see all of them here:
