Yes it was worth. At the start of BHD, i mine it solo and get 200 BHD in 2 month with 35TB. Sold 1 BHD for 0.4 ETH. So yes this was worth
But at moment it is really hard. If you are interested, please check the best PoC mining community with the biggest non chinese BURST Pool (and 8 other PoC Coins) and the only PoC Exchange

My Burst Miner running for 3 Years now. No problems with the drives
At least, one is able to earn some profit mining PoC (Proof of Capacity) coins if there are no costs involved when obtaining the drive. In other words, if you find around some spare HDDs from old computers for mining Burst, Sia, or Storj, you'll be able to "make free money". The main issue with HDD mining is the risk of centralization over the long term. It's no secret that there are big data centers from prominent companies around the world (mostly Google and Amazon) which are capable of obtaining most of the blockchain network's rewards. This model is terrible for the small miner (or the average person), which explains why HDD mining is still unprofitable these days.
You won't get any issues running drives for a very long time, if you rely on good brands like WD and Seagate. It's believed that desktop drives (3.5 inch) are much more durable than those available for laptops (2.5 inch). Using NAS-capable drives like the WD Red or the Seagate IronWolf, you'll be able to mine for years without hassles. But with today's costs, one could say this more of a hobby than anything else.
I appreciate the list of services available for HDD-mineable coins, though. Never heard about Foxy Pool or Foxy Exchange before, but it's nice to know that there is still support for these type of coins. I believe that the most popular coin that you can mine with HDD right now is Burst. Considering that flash drives (USB drives) are dirt cheap today, they could be real useful for mining Burst, or the ones mentioned previously. I believe that it'll be quite a fun task for the one who's passionate about crypto.
