I would say you nailed this one bullseye with one shot. I think your real concern isn't our "safety" it's yours. Sooner or later one of these alt-chains are going to replace Bitcoin if Bitcoin doesn't do some seriously needed updating and improvements.
You know it, I know it and so does everyone else.
Sometimes the truth isn't all warm and fuzzy, sometimes it's just plain brutal.

I think the updating and improvements of Bitcoin has referred to some commercial value like Bitpay which the bitcoin is commitment to keep secure and more valuable, indeed, the payment of Bitpay has become popular in North American such as Newegg in Canada.
