Do not invest in Bit4G.Com - as they will not allow you to cashout your bitcoin - once its in there they make excuses about blockchain "congestion", which is nonsense, as congestion would only DELAY not stop a coin transfer
At least everybody will know now that they are scam. I am reminding every ICO investors to do their own research too and do not invest more than they can afford to lose. Many scammers are littering the ICOs already in here. Now you are warned.
