Some great news came out from eos authority and Eos42 following yesterday's BP meeting. It seems as those EOS holders who failed to register for the mainnet snapshot, will likely have a solution coming there way in the near future. Roshan from EOS authority stated on telegram, "For all the unregistered token holders (The 0.3% of supply tokens that didn’t register and have no fallback). Some good news. If things go well, we will have something in 3 weeks time.The BPs discussed this item today. I presented a code solution and we have consensus from the BPs. We now have a fully automated process which will involve Ethereum Private keys, etc. I will keep this page updated." https://eosauthority.com/blog/what_to_do_if_you_are_unregistered_EOS_Token_holder. It has been indicated that BPs could have the option to use this solution for those of us with lost, non compromised private keys. EOS authority reported on telegram that for now its use is intended for unregistered holders, but if BPs think of extending its use there is a possibility more people could be helped. Lastly, it was emphasized to keep your ethereum keys SAFE!!!
