Jmma, all good points and well worth noting.
Similar to the the extension on voting for the 1:350 RS vote. Delcath and their minions monitored the activity and when they realized the vote would fail, they extended the voting period and started hassling the people who voted "No" by hiring a call center.
When the vote still failed they issued the Preferred Shares with voting rights to override the shareholders.
Same thing happened here. Delcath and their minions monitored the amount of subscription right bought and when they saw it was not enough they extended the subscription period. In my view when they realized it wasn't going to make a difference, the minions ran the price up (easy to do on low volume) to sucker more people into buying the subscription rights at $1.75.
Anyone that bought those rights and are still holding are down -84% so far on the investment.
Good Luck to You in 2019!
