So in that case Checkcoin will go on, no matter what.

I say CheckCoin stays and if BitSend stops we continue as community.
I hope BitSend continue but no information avalable so just have to wait.
The exchange rate is cheap imo if we take into account the coin survive.
If Bitsend stops then all the funds are lost. Anyhow they communicated that they will continue the project and that they just could not deliver so soon as they hoped for.
Most replies here are just made up and describe what-if situations, that has nothing to do with current status of Checkcoin.
