It's only at Yobit because on C-cex exchange the wallet is fine as I just transferred some coins onto C-cex and all work fine. Yobit always does this, another coin I invested in is also in wallet maintenance for no reason at all so I have to wait for them to fix it before I can withdraw my coins. Bios is still holding around the 90 sats price and has been for many weeks now. All we need is for the dev to come here and give us an update on where the roadmap is at and what is the plans for the future. Then we might see the price back over 100 sats.
