Hello,
I have moved the block.io adapter to the wastedump, where old extensions go to die.
There were complaints about block.io from some users and in fact some people were saying that block.io is a scam site. I don’t know if these are true or not. But my implementation was somewhat slow and buggy, and the CoinPayments adapter is superior in every way (is faster and offers more coins). This is why I stopped working on the block.io adapter and am not advertising it any more.
If you are using it without issues, you can continue using it.
with regards
