It is very strange, why first invest and then demand money back. It looks like it's just the machinations of competitors or scammers.

machinations, competitors, scammers !?
Not a tall ! when the team announce the delay of launching and to reimbourse the people who need go out, I take the decision to leave the project (and I'm free to do it !).But mean time I discovered that our wallets are stuck or frozen ! I wonder what can we do it if the token was launched ?They asked me to send their token back to initial address , but when I tried to do this (at least 4-5 times) the network return me failed transaction !
12 Jan 08:26-Failed to send 2..... OPEX to 0x088a3f324613d079a8b0e2dab59ed6c1d9889844-Failed-2...... OPEX
got the error on 04 till 12 Jan 2019; I assuming have no fault for this failed transaction, it is just a network feedback ! But I'm keept responsible for this and get no money back !
The team is not able to solve this situation since 15 December 2018 !!! Shall I believe all kind of advertising posted each week about opterium, or not !?

Have you tried to send tokens to another wallet? Ie create yourself another wallet and send them there.
