This must have been because of low income from the platform, it shows that miners are pulling out from the huge infrastructures mining operation which involves huge sum of money to set up a mining farm. Well, this must have been because of the market conditions, in which what they get is not as encouraging as before. I did a small research and got to know that the new mining platforms out there doesn't really needs a huge mining farm unlike the traditional ones, once you have a good device you're good to go. I'm more of a miner to trader and I must say in all my mining experience years am yet to see any mining platform that has low stress, interesting payout an huge potential like Veil.
