A good reminder, but I would rephrase it: Today is the last day to buy subscription rights if you want to subscribe to shares at a price of €0.1.
The pricing of the subscription right, the new share, and the old share is not efficient, and many have apparently arbitraged it. Currently, the new share can be bought at roughly a 1:1 price with the subscription right, but the old share is trading at its own prices.
I will watch until the very end to see if I can get the subscription right at a significant discount before the decision. I already bought one batch earlier at a suitable price of 0.03x.
