I'm also in a similar situation. Had blindly applied for the IPO without even looking at their valuations or GMP let alone RHP.
My thoughts at that time were that Paytm was kind of pioneer in fin-tech starting from demonetisation when govt indirectly promoted Paytm wallet, and was cashing every opportunity available in the digital space since inception. On top of that Paytm was hiring good talent for tech and business departments, so was confident that smart people would figure things out as I felt they were still innovative - Soundboxes, etc. (Although that doesn't translate to good business, my investments back then were based more on sentiments, evidently)
Since listing as the stock price kept crashing,I've been averaging out as my thesis that they have plenty of revenue streams including a trading platform and potentially can lend money to many small scale businesses was still intact.
While discussing with my one of my friend who works for an investment bank, he said:
"Don't put good money after bad money" which sounded like a golden advice at that time.
From then onwards I stopped pumping money and started to speculate on what they would come up with to make a profitable business. As more and more restrictions from govt came in its way I realised that I awarded too much for the future growth which may or may not even materialise.
I am planning to exit after the current bull run as I am unable to see a clear path to profitability even after 8 quarters and would revisit once they're back to form
