I've had the same concern as well... I have no evidence to call it a scam, nor do I have anything to validate it. I have had no issues withdrawing doge either. It won't let me withdraw my 32 XRP even though it claims you only need 20. Earlier today I tried to withdraw something else and it brought up some error too. So who knows. I'll just check it every now and then and see what I can do. It doesn't look like you have TOO much personally invested, so my recommendation would be to just place it in your bookmarks on your web browser and check it once a month or something. I would not recommend paying for any additional mining power though.
Yeah 😥.. I might have to just agree with you on that one thank you for commenting
I honestly don't trust anything in the crypto space. It's all bizarre. And if it's coming from the United Kingdoms, it's most likely a scam because they can purchase certificates for cheap to look legit. If you are looking for passive income right now, and willing to take a small risk of it being a scam, I recommend USI Tech (probably a scam) or Bitconnect lending (maybe? a scam?). I'm in both, they do have affiliate programs. I can send you a link if you would like to join, however, even though I'm in it... I don't necessarily recommend it.
