In a interview in 2017 (so in crypto terms a decade ago), Poramin Insom said he might come back.

Q: In 2014, you had founded Vertcoin which enjoyed some success, what was your vision of Vertcoin and describe your experience? Are you satisfied with what you achieved with Vertcoin?

My vision about Vertcoin originally was a coin that focused on ASIC resistance. I have learnt a lot from Vertcoin and I used this knowledge to develop Zcoin. I do want to return to developing Vertcoin in the future, but my current focus is on Zcoin especially when I do have an obligation to my investors.


I do not know of the current team even wants that https://vertcoin.org/team/

I am happy Vertcoin is still alive and well. GPU mining FTW!
