This is not the first time if you have followed the Bitsum project since its beginning. Online wallet off sometimes, then on again, pools work then die and start again. Personally, I think this one is very normal cycle in crypto sphere. Technical issues occur and gone away. Please give Bitsum developers more time, we will see good things.
if you got airdrops from Stellar some years ago, extremely easy to got them at that point, you actually own tons of fiats. What happened, most of receivers sold their coins immediately or several weeks/ months later, to get very little fiats.
Good luck, boys.
