I have over 800,000 HE and SE coins. Unfortunately, the price of my coins seems to be dropping faster than my earnings; so the us dollar value of my collection is quite bleak.

In addition to staking; one can add their coins to diesel or simply actively trade the coins on the market. I like to keep a large number of active buy and sell bids on the HE market. Adding coins to the market increases the liquidity of the market.
