where can I get the NEW Hardware? to make profit
No, you're not doing anything wrong. If it was easy to make a profit, everyone would do it, raising the difficulty, and bringing the profit to zero. Only those with the lowest cost of electricity, the lowest cost of capital, and who can get the best deals on high-end ASIC miners can make a profit. And even then, only by taking the risk that the difficulty or price will not change in ways they didn't expect.
