Yup, essentially building one's wealth (not the sole method) by leveraging on the potential of Cryptocurrencies 2.0 is a no brainer:

1. You earn free cryptocurrencies/tokens through your usages of specific applications
2. It's FREE because you don't need to invest any capital beforehand in order to gain these cryptocurrencies/tokens

Basically, you WIN free money and you LOSE nothing because you don't risk anything!! And STEEM Blockchain is the perfect fit for this wealth building strategy, so keep steeming people!!
