The great thing about this program is that you can run their browser on as many devices as you want. With just one device, you can earn $65 per year assuming you leave it running constantly. The only condition is that you must have each device running on a unique IP address. You can either get multiple IPs or request a family member or friend run the same link for you.
stREITwise offers a hybrid investment between traditional REIT fund investing and the new crowdfunding. The fund is like a real estate investment trust in that it holds a collection of properties but more like crowdfunding in its management. The fund has paid a 10% annualized return since inception and is a great way to diversify your real estate exposure.
You pay two main types of taxes on earned income, Social Security/Medicare taxes (called FICA, OASDI, or payroll taxes), and federal and state income taxes. The payroll taxes that are automatically taken out of your paycheck have two components. First, 12.4 percent of earned income is paid to Social Security. Your employer pays half of this tax, and you pay half. If you are self-employed you'll pay the full 12.4 percent, however, the "employer" portion of 6.2 percent is generally tax deductible.
The IRS requires REITs to pay out at least 90% of its income to shareholders.  Thus, REITs tend to be higher yield since a large fraction of the earnings come out as dividends, which may be beneficial for certain income oriented investors.  The flipside is the tax cost for investing in REITs since income must be distributed and as a holder the taxes flow through to you.
If you sell an asset like a stock or mutual fund at a price that is higher than the amount you paid, the difference or profit you realize is a capital gain. Capital gains are divided into two categories: short-term gains and long-term gains. Short-term gains are profits realized from the sale of assets you hold a year or less, while long-term gains are profits gained from selling assets you hold longer than a year.

I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.
