ThomasV is only develop Electrum for bitcoin, but there are some others wallet based on Electrum which have existed for years and have been shown as trusted. I have personally used ElectronCash for BCH, ElectrumLTC for Litecoin and ElectronDash for DASH. How much can I see on their official sites, developers of this wallets are active and new releases follow current events.
My opinion is that your advice has no legitimate basis, maybe you not trust in something for your own personal reasons, but that is not the reason why others should avoid something.
Not the wallets have to be trusted, but the developers.
As for my self, i do not trust a random developer (Calin Culianu ??) who decided to voluntarily develop a free wallet for a currency which is doomed to fail and which was obviously just an attempt of a few people to get rich quick.
I never said people should avoid it.. there is a difference between
not trusting and
avoiding.
I am just saying that there isn't a single reason why he should be trusted.
Also.. the instructions to verify the files which are on github also urge to think that he is not the brightest person alive..
Instead of simply signing the files OR creating 1 signed text file with the hashes inside.. he created 1 signed text file per downloadable file containing 1 hash each
