With the help of CoinExchange.io admin we found problem, working on solving.
I will provide more information + explanation why deposits/withdraws was disabled tomorrow.
-------------------
Some big updates upcoming.
I decide to focus on ICO tracker + Ethereum token, smart contracts creation for Hubcoins only (and will not receive any other payments) as getting many orders after winning the Hackathon.
I got near 5 emails on email about ICO tracker, peoples want to add/edit their services or asking me how to pay for higher place.

I would add Hubcoin on another exchanges later and going to provide buy/sell options on Hubcoin.io website too.
Also i am going to buy some Hubcoins at 7500 satoshi and support price a bit, as have many orders for smart contracts writing and wallet integration now.

Free explorers service + websites/hosting is frozen for now, will return to them a few months later.
But if anyone will ask hosting / explorers, i will help them as it was promised.
