Oh I am quite happy with it at this point. I hope as BTC goes up Raven will follow and like you said sell all at 25cent and cash out - if it reaches that high next time 
My moto has always been hold as much coins as you can but sell coins you need to cover your monthly expenses.
You could also trade your RVN for a basket of coins in order to diversify. But you are in an enviable position even at 3.8 cent RVN. Most miners years ago sold 99% of their coins instead of HODLing them and making millions. I personally missed out on hundreds of thousands of DOGE, DASH, ETH and LTC because I never saved up enough of the coins. From now on I'll never repeat that mistake again and I'll keep mining during the bear market.My moto has always been hold as much coins as you can but sell coins you need to cover your monthly expenses.
My moto has always been sell enough coins you make to pay for bills + have a decent life ( changes daily/monthly due to value of coins i mine - atm raven and ETH ). So far I have always been in profit, had friends that lost 100s of thousands because they waited some insane numbers they have set, like one friend that waited for ripple to get to 10USD and then sell.
