Yes it is down here and it should be down for everyone based on https://downforeveryoneorjustme.com/bithobo.com
It has been more than a week since you got your issue related to your withdrawal and their claim that you exploit their game without valid evidences unfortunately.
Lets wait for more few days, if the site is not coming back without any updates from the OP in this thread then I think you have no chances to get your deposited money back.
It is obviously bad as they are new site but seems to be irresponsible for a case worth less than $100.
