Yes I saw the original post and there is much discussion about it in the BitShares Telegram channel. Two things:
- is it really true or just FUD
- if it is true it does not make BitShares a scam but just Arise. BitShares has been a functioning Blockchain for years with many projects being built on it. Arise is but one of them.
Thanks for your answer. Because you are much more familiar with BTS you might be right. One further indicator could be that the posting is deleted meanwhile, @valth wrote (see above).
