I am scaling them up:
I started up two different mining farms (where I own the machines)
I have started up a crypto-copy-trading
I am partnering with international companies that pays me in cryptos (which I do not fully liquidate)
I am buying every month some BTC, ETH and other major cryptos to be diversified in my holding portfolio
I am staking ALGO (also as a governor), TRX and Hive
I am investing in DeFi, both in the yield stage and in tokens related to it. 
Creating NFTs for an artist to accumulate more ETH
Blogging here and there

These are the ways I am using to accumulate cryptos
