Remember SBD is a pegged currency. Meaning that it will eventually lose value. It is true everyone wants to get SBD now. This is because there is a very limited supply. The way SBD is produced is by work here on Steemit , Busy, Dtube, Dlive, etc. The key to earning SBD is understanding there is a "Return On Investment".

Invest "X" amount of SP then add work here by blogging and you can multiply "X" by at least 25%. You will partially get paid in SP and partially in SBD.

If one invests 0, then multiply 0 by 25% and the return = 0.
If you want to earn SBD, then invest in SP. The more SP you have, the more SBD you can earn.

Think of it like owning a portion of a business. If you decide to partially own a business with your friends. You decide to invest 0 in the business, therefore you will will have 0% ownership. When profits come, you will get your portion of the profits which is $0. If you happened to buy 25% of the business and put into the business 25% of the effort to run it, then it would be fair to take 25% of the profits.
