Post 4 Update: When fun and profit come together it's a wonderful thing. Three months ago while searching for my next altcoin venture I stumbled across Rain. After looking at what I could find on the coin, exchanges(limited), volume(tiny but charting almost linear growth) and community I decided to download the wallet and start staking rewards. Since then, RAIN has been running up in both price and volume even on days where bitcoin BTC surged up driving almost all altcoin prices down. After watching my initial investment of approx. $813. USD hit $8,000. I decided yesterday to withdraw it($845ish) leaving me with a staking wallet with 68,519 coins worth over $7,100.
To sum my experience up so far, RAIN has been one of my top three staking coin performers over my 3 1/2 years in crypto and I'll continue to hang in there for now.
Investing in cryptocurrency/digital currency is risky business so please do your own research and never use money you can't afford to lose.
