The current wallet does stake, as LEOcoin is still a mixed POW/POS generated digital currency. However, the stake interest in the new wallet will be higher as with the old one, who has only a stake interest of 4% of the POW created LEOcoins. New stake interest will be going up as high as 20%, depending on your stake size.

If you e.g. have a wallet with 10,000 LEOcoin, you will receive 15% stake interest, or 1,500 LEOcoin annually. To currently mine 1,500 LEOcoins, you need a RIG (5xR280x) working one year, using about 7,000 Kwh, 'producing' a nett worth of 1,500 * 0,20€ = €300, without electricity cost being covered.

If you however purchase 10,000 LEOcoin for 2,000€, you get 300€ stake interest. Without electricity. After 7 years, (LEOcoin price remaining unchanged) you have your investment back (and no depreciation on your RIG).

This is what it is. If you like it or not, is up to you.
